Published: July 2018

Background: The objective of this study is to assess the efficacy and safety of Fahmy's four quadrant suture technique (FFQS) in controlling blood loss during cesarean delivery for placenta previa (PP).Methods: The study was carried out in a tertiary University Hospital between January 2017 to December 2017 involved 12 women with heavy bleeding occurred after removal of the placenta from the lower section during cesarean delivery for PP. The FFQS technique consisted of two sutures to ligate the uterine branches on both sides and two sutures on the anterior and posterior wall of the lower uterine segment. Details regarding the management and maternal outcomes were recorded.Results: The mean age of the study participants was 29.58±5.29 years and the mean parity was 2.25±1.14. The mean gestational age at termination of pregnancy was 36.91±1.38 weeks.  The mean duration of the whole surgery was 78.75±43.28 minutes, while the mean duration of FFQS technique was only 10±2.09 minutes. The technique was exclusively effective in 8 out of 12 cases (66.67%) while 2 cases needed bilateral internal iliac artery ligation and 2 cases needed hysterectomy. The mean amount of blood loss in all cases was 2433.33±833.76 ml. the mean amount of transfused packed RBCs was 3.92±1.68 units and fresh frozen plasma (FFP) was 3.42±1.44 units. All cases had uneventful postoperative course and no mortality cases in present series.Conclusions: The new technique; FFQS represents a rapid, effective, and inexpensive opportunity for women with bleeding from the lower segment of uterus due to PP. This simple procedure should be attempted before other complex measures to achieve good hemostasis.

Authors: Arshiya Khan , Meenakshi Srivastava
Published: July 2018

Background: Preeclampsia (PE) is a disease specific to pregnancy affecting many bodily systems. This is characterized by high blood pressure and proteinuria after the 20th week of pregnancy. The objective of this study was to evaluate of association of vitamin D insufficiency with gestational hypertension in pregnant women.Methods: This was a cross-sectional study. A total of 104 pregnant women were included in the study. The diagnosis of gestational hypertension was confirmed using the “Report of the American College of Obstetricians and Gynaecologists’ Task Force on Hypertension in Pregnancy” criteria. Based on these criteria, patients with systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg (measured after a period of rest of four hours, twice daily) and proteinuria (≥300 mg protein/24 h) were diagnosed as gestational hypertension.Results: Vitamin D deficiency was found among 78.9% (90/114) women. There was no significant (p >0.05) difference in age of women between vitamin D deficient and sufficient. Vitamin D level was significantly (p = 0.0001) lower among the women between Vitamin D deficient (15.93±4.66) and sufficient (35.70±3.25). There was no significant (p >0.05) association of Vitamin D level with parity, family history of hypertension, blood pressure, gestational age and fasting blood glucose. There was significant (p = 0.0001) difference in BMI between Vitamin D deficient (30.10±4.95) and sufficient (24.04±2.75). Tobacco consumption was also associated with the level of Vitamin D. There was significant negative correlation between BMI and Vitamin D level (r = -0.56, p = 0.00011).Conclusions: The present study demonstrates that vitamin D plays a role in the ethology and pathophysiology of gestational hypertension. Among the population having the risk of vitamin D deficiency, the risk of pregnancy induced hypertension may be decreased through vitamin D supplementation.

Authors: Kale Ashish , Kale Ashwini
Published: July 2018

Background: With advances in assisted reproductive techniques its becoming increasingly important to identify pregnancies having a potential of adverse outcome in the form of per vaginal bleeding or early pregnancy loss. The objective of this study was to find out whether the value of luteal phase progesterone can be used as a marker to predict the possibility of per vaginal bleeding and early pregnancy loss in cases conceived by in vitro fertilization (IVF) and embryo transfer (ET).Methods: A total of 40 women of age less than or equal to 40 years undergoing IVF and ET were included in this study depending upon inclusion criteria. Patients were excluded if they had any factor defined as exclusion criteria. on D14 after embryo transfer B-hCG was done in all the patients. If B-hCG levels were found to be ≥ 100 mIU/ml then serum progesterone levels were also done. B-hCG levels were repeated after 48 hours. Pregnancies were followed up and correlation between suboptimal rise in serum progesterone levels and adverse pregnancy outcome was studied.Results: Mean Beta-hCG and Serum progesterone levels on D14 of embryo transfer were found to be 388.86±34 mIU/ml and 54.24±4.32 ng/ml respectively. A repeat B-hCG and serum progesterone level 48 hours after initial estimation showed mean B-hCG and serum progesterone level to be 598.80±52.12 mIU/ml and 72. 24±5.24 ng/ml respectively. Out of 40 patients 26 patients showed >30% rise in serum progesterone level while 14 patients showed less than 30% rise in serum progesterone level.Conclusions: Suboptimal rise in serum progesterone level (<30%) was associated with increased incidence of adverse pregnancy outcome in women conceived after in vitro fertilization and embryo transfer.

Published: July 2018

Background: Maternal and perinatal mortality and morbidity remains high during pregnancy in the presence of eclampsia, it can have severe adverse effects on mother and the fetus. So, its management should be a top priority. The objective of the present research was to study the effect of magnesium sulphate in control of imminent eclampsia and eclampsia.Methods: 19 cases of eclampsia and 185 cases of imminent eclampsia were treated with standardized magnesium sulphate. The outcome measures in terms of recurrence of convulsions, maternal and neonatal outcome, etc. were seen.Results: Most common age group in both the groups were 21-30 years (i.e. 78.9% with eclampsia and 75.7% with imminent eclampsia). In both the groups, majority of the women were primigravidae. In eclampsia group, 9 (47.4%) women had 1 episode of convulsion, 8 (42.1%) women had two episodes of convulsions, 1 (5.3%) women each had 3 and 4 episodes of convulsions, while there were no convulsions in imminent eclampsia women (‘t’ value = 28.558, df=202, p=0.000). Vomiting and headache (94.7%) were the most common premonitory symptoms in eclampsia group, followed by edema in 68.4% women, while in imminent eclampsia 64.9% women had headache, 57.8% women had edema and 43.2% had vomiting. Recurrence of convulsions were seen in 4 (21.1%) women of the eclampsia group even after giving maintenance dose and additional dose of magnesium sulphate. 1 (5.3%) death was seen in eclampsia group and none in the imminent eclampsia group. Neonatal mortality in eclampsia group (47.4%) was higher than imminent eclampsia group (11.7%), which was statistically significant (Z value = 3.05, p=0.002).Conclusions: Magnesium sulphate regimen was effective in control of convulsions in eclampsia and as prophylaxis in imminent eclampsia.

Authors: Amin Kinnari Vilaschandra , Nadkarni Purnima , Singh Pooja Nadkarni , Singh Prabhakar
Published: July 2018

Background: Whether serum progesterone (P4) level on the day of human chorionic gonadotropin (hCG) trigger is related to the outcome of artificial reproductive technology (ART) is still a debatable issue. The objective of this study was to evaluate relationship between serum Progesterone levels on the day of hCG trigger and ICSI outcome.Method: This was a retrospective, non-interventional, observational, cohort study of patients undergoing ICSI at 21st Century Group of Hospitals, Killa Pardi and Surat, Gujarat during the period of January 2018 to March 2018. Patients with age group of 20-40 years who underwent ICSI-ET using GnRH antagonist flexible protocol during this period, had obtained 2 or more MII oocytes during retrieval and had at least one grade I embryo transferred were included in this study. Women using donor oocytes were excluded. Serum progesterone levels were analysed on day of hCG trigger. Total 165 patients were included in the study. They were divided into two groups, those with β-hCG less than or equal to 1.5 ng/ml and those with β-hCG more than 1.5 ng/ml. Student's t test and Chi square test were used to compare the clinical pregnancy rates between two groups.Results: Clinical pregnancy rate decreases with increase in serum progesterone levels on the day of hCG trigger. Patients with serum progesterone levels ≤1.5 ng/ml had significantly higher clinical pregnancy rates than those with progesterone levels >1.5 ng/ml (45% vs 6%; p :<0.001).Conclusion: Pre-hCG rise in serum Progesterone concentration does not affect the oocyte quality. But, it significantly decreases the chances of implantation and the clinical pregnancy rates.

Authors: Korde Vaishali R. , Barse Sharin P. , Barla Jaya S.
Published: July 2018

Background: Thyroid dysfunction is known to be the commonest endocrinological disorder in pregnancy. A range of adverse outcomes in pregnant women and the fetus have been reported. These can be prevented if the thyroid dysfunction is diagnosed and treated as early as possible. There are limited studies conducted on the prevalence of thyroid dysfunction in pregnancy in India. Hence, this study was conducted for assessment of the prevalence of thyroid dysfunction in pregnancy.Methods: The present study is a prospective study conducted in the Department of Obstetrics and Gynecology, MIMER Medical College and Hospital, Talegaon, Dabhade, Maharashtra. The total sample population comprised of 705 pregnant women with uncomplicated singleton intra-uterine pregnancy. All participants were screened by estimation for serum TSH in first trimester.Results: The prevalence of thyroid dysfunction in the present study is 13.9%. Of this, prevalence of hypothyroidism is 12.76% and that of hyperthyroidism is 1.13%.Conclusions: With this study, we conclude that there is high prevalence of thyroid dysfunction in pregnancy even in rural population. Thus, a universal screening helps in early diagnosis and preventing the aftermaths of thyroid dysfunction in pregnancy.
Correlation between ultrasonographic, hysteroscopic and histopathological findings in patients with abnormal uterine bleeding
Authors: Bhatiyani Binti R. , Dhumale Shrikant , . Pandeeswari , Bashani Dolly
Published: July 2018

Background: Menstrual disorders are common indication for medical visits among women of reproductive age and heavy menstrual bleeding affects up to 30% of women throughout their reproductive lifetime. This study aims at evaluating the different causes and, the clinical presentation of AUB and to compare the role of hysteroscopy, ultrasonography and histopathology in patients with AUB.Methods: 100 women above 45 years of age, presenting with abnormal bleeding per vaginum were evaluated. All patients underwent transvaginal scan to note down the endometrial thickness and to rule out uterine and adnexal pathology. All the patients underwent diagnostic hysteroscopy, followed by a biopsy of the endometrium using a curette. The endometrium was sent to the pathologist. Findings of these diagnostic modalities then correlated.Results: Incidence of AUB was present between the age groups of 45-49 years of age (66%). The commonest presenting complaint in this series was menorrhagia or heavy menstrual bleeding (60%). The finding of thickened endometrium as the most common abnormality on USG (44%) and also on hysteroscopy (45%). As per present study the sensitivity of hysteroscopy is 97.78% and specificity was 34.55%, the negative predictive value of the test is 95%.Conclusions: TVS may be the first line of investigation while evaluating the endometrium in a perimenopausal AUB. It helps to triage the patients into high risk or low risk. Endometrial thickness >4mm as per the present study needs further evaluation. Patients with endometrial thickness less than 4 mm can be reassured. Hysteroscopy is the gold standard in the diagnosis of focal pathology like sub mucous fibroid, polyps or anomalies. Histopathology probably is an indispensable tool specially to rule out premalignant and malignant conditions. Thus, all the modalities instead of being competitive to one another, are complimentary to each other. For complete evaluation of patient with AUB all the three modalities should be used together to come at exact diagnosis.
Nonimmune hydrops foetalis (NIHF): value of fetal autopsy and comparison with ultrasound findings
Authors: G. Umamaheswari , T. Ramya , V. Chaitra
Published: July 2018

Background: Nonimmune hydrops foetalis (NIHF) is a terminal catastrophic event of pregnancy caused by numerous diverse etiology. The aim of this study was to assess the significance of foetal autopsy and to compare the prenatal ultrasound (USG) and foetal autopsy findings in cases of NIHF.Methods: All perinatal autopsies performed at the department of pathology between March 2011-February 2018 were retrospectively reviewed. Of the received 130 autopsies, twenty cases of NIHF were identified, records of which were collected and correlated with maternal medical history, prenatal imaging and autopsy findings.Results: The malformations with hydrops foetalis were classified according to the involved organ system. They were cardiothoracic (7/20 cases), genitourinary (3/20 cases), gastrointestinal lesions (1/20 cases), chromosomal (4/20 cases) and multisystem anomaly/syndromic association (5/20 cases). Complete agreement between USG and autopsy was seen in 8 (40%) cases. In 5 (25%) cases autopsy findings were in total disagreement with USG diagnosis. The rest of the 7 (35%) cases, autopsy revealed additional information and changed the recurrence risk in two cases.Conclusions: Present study demonstrates the high rate of discordancy between USG and autopsy examination in cases complicated by NIHF. Foetal autopsy confirms the USG findings (quality control/audit), adds additional findings or changes the final diagnosis, which helps in redefining the recurrence risk and plausible genetic counselling for future pregnancies. Hence present study underscores the need for autopsy in all cases of NIHF.

Published: July 2018

Müller cysts are alterations in the development of sexual cords and remain as malformations associated with them. They can occur in many morphological varieties. In the case of pregnancy, vaginal tumors can complicate labor because they cause obstruc-tion of the canal. During labor, these alterations can complicate the diagnosis and proper management of pregnancy. A 22-year-old female, who came to the hospital at 30.1 weeks of gestation for the first time, due to obstetric pain, vaginal tumor was detected, the patient triggered preterm labor, which did not address medical management based on oral and intravenous uteroinhibitors, so a cesarean is decided, later in the puerperium magnetic resonance was performed finding a defect in the vaginal wall, compatible with probable Müller's cyst. Due to its low frequency but high impact on pregnancy, vaginal tumors are a diagnostic and therapeutic challenge, due to their embryological origin should be detected and advise on the consequences of them. As a result, some other alterations may coexist, which is why complementary studies are essential. In the pregnancy protocol, the proper location of the cysts guides us to a specific embryological origin, as well as a preventive intervention can be planned in cases like this. If these patients are asymptomatic, surgical intervention is not required, much less during pregnancy unless an obstetric indication for interruption is determined.
Fibroid with unilateral streak ovary in Mullerian Agenesis!a rare case report
Authors: Malik Renuka , Goyal Avani , Bhardawaj Meenakshi
Published: July 2018

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a rare anomaly (1/5000) associated with uterine and vaginal aplasia with normal ovaries. A fibroid in a normal uterus is common but a fibroid arising from rudimentary horn in Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is very rare. It is also rare to have the association of unilateral ovarian dysgenesis in MRKH. A 37 year old married female with primary amenorrhea presented to the OPD of Dr. RML Hospital with abdominopelvic mass for one year. She was phenotypically normal looking and there was no other associated cardiac, ocular or skeletal abnormality. A large 15 × 15 cm abdominopelvic mass was present in suprapubic area which was firm in consistency and non-tender. A Two and a half inch long blind vaginal pouch was present with absence of cervix and uterus. A provisional diagnosis of solid ovarian tumor in MRKH syndrome was made. Her investigations -Serum FSH, LH, estradiol and tumor markers were normal. Her ultrasound and MRI reported a fibroid with normal ovaries. Laparotomy revealed absence of uterus and cervix and a large fibroid arising from right rudimentary horn with left streak ovary. Right ovary was enlarged to 4 × 4 cm, showing multiple small follicles. Fibroid along with the rudimentary horns and the streak ovary was removed, preserving the normal right ovary. Histopathology confirmed the diagnosis of leiomyoma in rudimentary horn with left streak ovary, making it class1 type b anomaly under American fertility society classification. Preoperative assessment of rare anomalies can be different from intraoperative findings in certain female reproductive tract anomalies. Awareness of rare combinations can help in judicious management of such cases.

Authors: Chauhan Gaurav , Singh Vivek , Phadke R. V. , Yadav Sapna , Gupta Abhishek
Published: July 2018

Postpartum cerebral angiopathy (PCA) is a rare cause of stroke in the puerperium. It usually presents with episodes of headache, seizures and neurological deficits in early post-partum period in normotensive females. CT, MRI and catheter angiography may demonstrate segmental vasoconstriction that often resolves spontaneously. PPA is generally regarded as a benign, non-relapsing and reversible disease process. We present a clinico-radiological correlative case of isolated corpus callosal hematoma in a post-partum normotensive female with evidence of intracranial vascular spasm and luminal irregularity on CT and catheter angiography. Follow up MR angiography showed resolution of the vasospasm and luminal irregularity. Patient was managed conservatively and showed resolution of the symptoms in follow up visit on 8th week.

Authors: Khan Bushra , Sharma Ramesh , Borkar Milind A.
Published: July 2018

Background: Alopecia Areata is a T-cell–mediated autoimmune, often reversible disease in which the gradual loss of protection provided by immune privilege of the normal hair follicle plays an important role. It manifests as smooth, slightly erythematous (peach color) or normal-colored alopecic patches with short broken hair at the margins. It involves scalp most commonly, although other regions of body may be affected. Platelet rich plasma is an autologous concentration of platelets with a greater count in a small volume of plasma. Study aimed to evaluate the safety and efficacy of PRP therapy in Alopecia Areata.Methods: In this randomised, placebo controlled, split patch study, 30 patients of AA were recruited and injected with 1-1.5ml of autologous PRP made by double spin method into half the bald patch area and other half with placebo using insulin syringe once a month for 3 months. Outcome was assessed at the end of study by clinical photographs as regrowth of hair, dermoscopy findings as reduction in black dots, yellow dots and exclamation hair and Physician and patient self-assessment score.Results: Administration of autologous PRP has led to observable improvement in 20% case of PRP and only 3.3% of control cases. Decrease in number of dystrophic hair and hair regrowth with PRP was seen in 20% cases and in 17% patches.Conclusions: PRP in our setting was found to be minimally effective, but more efficacious than no treatment, and safe for AA patients.

Background: Premenstrual Syndrome (PMS) is a common psychosomatic disorder which affects 30%-50% of women in child bearing age. Symptoms’ have devastating effect which starts early in life. So, the study was conducted to estimate the prevalence of premenstrual syndrome (PMS) and its association with menstrual profile among female students of colleges situated in Ujjain city.Methods: Observational follow-up study was conducted at 4 colleges selected by convenience sampling located in Ujjain city. PMS and menstrual profile related data from 250 girls (18-25years) who consented to participate were collected using a modified version of daily record of severity of problems for atleast 2 consecutive menstrual cycles. Diagnosis of PMS was made using ACOG criteria. Data analysis was done using SPSS version 16.0.Results: The prevalence of PMS was 39.6% and was found to be negatively associated with any history of mothers having menstrual problems.Conclusions: Frequency of PMS is relatively common in young girls and has negative association with any history of mothers having menstrual problems. Measures should be adopted so that mothers can condition their daughters about premenstrual symptoms which will influence the quality of life of young females.

Memórias de violência no Twitter: sensibilidades do estupro a partir de #OsDiasEramAssim
Authors: Da Conceição Juara , Borges Rosana Maria Ribeiro
Published: July 2018

Ao refletirmos acerca do Twitter, tende-se a destacar suas questões de efemeridade, sobretudo no que diz respeito ao seu fluxo de comunicação. Entretanto, o que buscamos neste trabalho é traçar uma relação de perenidade entre memória, narrativas seriadas ficcionais e o Twitter. O corpus de análise serão as postagens filtradas do Twitter a partir da hashtag “#OsDiasEramAssim” e também da palavra “estupro”, pois o que buscamos em nosso trabalho é compreender quais as memórias e significações dessa violência, a partir da série “Os Dias Eram Assim” da Rede Globo (2017) e sua reverberação de sentido no Twitter. A análise parte do entendimento de que as redes são estruturas sociais de caráter coletivo (Castells, 1999), o que vai ao encontro com os aspectos de memória destacados por Nora (1993), que fala da relação entre coletividade e memória e de sua natureza grupal e viva. Para tal, compreendemos a hashtag como extensão lúdica e memorial da narrativa (Fechine, 2011), o que nos permite refletir acerca da memória e sua relação com as redes informacionais e as narrativas de ficção. Entendendo que as narrativas ficcionais balizam o imaginário social (Maffesoli, 2001) e a cultura da sociedade, traçando ao longo da história aspectos de identidade e identificação.

Published: July 2018

The wind energy generation is the huge driver behind the push for supergrids and cross-border infrastructure for renewable energy systems. To improve the energy system and reduce deployment costs, the wireless communications can arise as a powerful tool in this new scenario. However, the wireless technology for transmitting control information to wind generator requires special attention to avoid any damage to the generator and to the energetic plant caused by transmission errors. In this context, this work proposes a wireless coded power control system for variable speed wind doubly-fed induction generators. The proposed controller is based on the adaptive neuro-fuzzy inference system and it uses the vector control technique to independently control the active and reactive power. The wireless communication system employs QPSK digital modulation and LDPC coding scheme to reduce the transmission errors and the overall system latency. In addition, it is presented its feasibility analysis and impact to the overall system by investigating the control performance in operational conditions at AWGN and flat fading propagation channels.

This paper proposes a technique to suppress saturation in series transformers applied to dynamic voltage restorer (DVR) systems. The method consists in correcting the voltages which are injected through the transformers into the power system to compensate voltage sags. It restricts the compensating voltages during the sag whenever it predicts that a maximum limit for the flux-linkage is about to be surpassed. The prediction takes place at the beginning of the voltage sag. Moreover, the method always allows a level of sag compensation even if it prediction for exceeding flux limit is confirmed. Simulation and experimental results show the effectiveness of the method.

Published: July 2018

In this paper a direct power control strategy for a doubly-fed induction generator by using an artificial neural network controller with the multilayer perceptron structure is presented. The control variables direct- and quadrature-axis rotor voltage signals are directly generated by proposed controller from both stator current and voltage that are measured by Hall sensors. The input variables of the control system are the rotor speed, the active and reactive power references and their respective errors. The proposed control strategy allows that the converter connected to the rotor terminals operates with constant switching frequency which simplifies the design of the AC harmonic filter and as well as prevents their power losses. To validate the proposed control strategy, digital simulation and experimental tests are performed for a 2.25\,kW doubly-fed induction generator. A TMS320F2812 DSP is used to implement the neural network controller.

In recent years, the development of new technologies is requiring power supplies with wide dc conversion range. In this paper an alternative solution is presented, the properties of the new soft- single-switched (SSS) Boost converter with voltage ratio that are quadratically dependent on duty cycle are discussed. The converter is a zero-current-switching (ZCS) during the turn-on period and a zero-voltage-switching (ZVS) during the turn-off period. The operating principle of the proposed converter is explained; its operating modes along with key waveforms are shown. Moreover, a complete simulation and experimental results have verified the feasibility of its applications in renewable energy systems.

Published: July 2018

Apresenta-se uma estratégia para a equalização de potência em uma associação em paralelo de circuitos ressonantes com dispersão de parâmetros. O ajuste da sintonia é feito por meio de compensação série utilizando a técnica de síntese direta de reatâncias. Além disso, a presença de transformadores traz a necessidade de impedir sua saturação, o que também é feito por uma compensação eletrônica. Como aplicação, considera-se um sistema para geração de ozônio, com a conexão em paralelo de diversos conjuntos formados por transformador e dispositivo ozonizador, alimentados por um único inversor. Resultados de simulação e experimentais mostram o comportamento dos circuitos e das estratégias de controle propostas.

Pesquisas recentes têm apontado para os LEDs como a tecnologia mais eficiente e durável a ser utilizada em iluminação, no entanto, estes requerem um conversor com a finalidade de controlar a corrente elétrica que flui através da lâmpada a LED. Neste contexto, este trabalho apresenta a análise, projeto e implementação de um conversor com ampla faixa de tensão de entrada chamado Boost-Buck Quadrático. Este utiliza um único interruptor e uma estratégia de controle de simples implementação, e foi projetado para acionar uma lâmpada a LED de 12 W utilizada tanto em sistemas de iluminação de emergência, como iluminação convencional. A principal característica deste sistema é o fato de poder ser alimentado tanto por uma bateria (12 VCC) quanto pela rede CA convencional (90 a 240 Vrms). Para comprovação dos resultados teóricos, são apresentados os resultados experimentais obtidos através de um protótipo construído em laboratório.

O objetivo deste trabalho é o desenvolvimento de uma metodologia de análise das coordenadas de cromaticidade em LEDs RGB, considerando a influência da temperatura de junção nas mesmas. Uma revisão teórica dos conceitos de colorimetria é realizada, bem como uma demonstração do equacionamento de fluxo luminoso que considera o efeito das características térmicas e elétricas dos LEDs. Os resultados das equações que representam a temperatura do dissipador e da junção dos LEDs são comparados com simulações em elementos finitos e com medições experimentais. A equação do fluxo luminoso é relacionada com as matrizes dos valores tristímulos a fim de obter- se uma relação precisa entre as condições de operação do LED e a cor desejada. Por fim, ensaios com o objetivo de comprovação dos resultados teóricos em comparação com os resultados experimentais são apresentados.

Published: July 2018

Este trabalho propõe um conversor para o acionamento de diodos emissores de luz (LEDs) de potência. Em contraste a propostas convencionais em corrente continua, a potência provida aos LEDs é estabilizada através de um capacitor comutado. O conversor proposto difere dos conversores tradicionais baseados no capacitor comutado, pois utiliza um pequeno indutor para possibilitar a comutação suave nos interruptores. Após uma análise qualitativa e quantitativa, a utilização do conversor para a equalização de potência em vetores de LEDs é proposta. O circuito proposto é validado através resultados experimentais de um protótipo de 55 W. O protótipo apresentou um rendimento de 87%.

Authors: Rodrigues Cláudio R. B. S. , Almeida Pedro S. , Soares Guilherme M. , Braga Mateus F. , Braga Henrique A. C.
Published: July 2018

This paper deals with the problem of current sharing in parallel strings of LEDs. As there is no guarantee that the string voltages are the same, some strategy for equalizing their currents must be used. This ensures that the luminous fluxes emitted by the strings are very similar. To address this issue it is proposed a small and simple linear topology that can be used on a number of series- associated LEDs, working as a constant current source for each string. Only four components are used in the arrangement, and a low dependence on transistor parameters is observed, ensuring good current regulation. Mathematical description and an analysis of the stability of the circuit are provided, as well as experimental results.

Este trabalho apresenta a modelagem, o projeto de controle e a implementação de um reator eletrônico microcontrolado, baseado na conexão diferencial entre conversores CC-CC, para lâmpadas de descarga de vapor de sódio em alta pressão. A topologia final do reator é caracterizada pela integração do estágio diferencial (composto por dois conversores do tipo flyback) a um conversor buck-boost usado como estágio de correção do fator de potência. Com base nos modelos obtidos através da modelagem por espaço de estados, realiza-se o projeto de duas malhas de controle: uma malha externa de potência e malha interna de corrente. Os controladores foram implementados digitalmente em um microcontrolador de baixo custo. Um protótipo de 70W alimentado por tensão eficaz de rede de 220V foi construído para comprovar a ideia proposta.

This work presents the study and implementation of a multi-input dc-dc interleaved boost converter used in solar photovoltaic systems. Initially, a comparative analysis between two popular techniques used to track the maximum power point is performed to demonstrate whether controlling the PV array voltage or current has significant impact on the solar energy conversion into electricity. Due to their popularity, perturb and observe and incremental conductance are chosen and evaluated through simulation tests. Considering that the results obtained with both techniques controlling either the voltage or the current of the modules are similar, incremental conductance is implemented in and dc-dc interleaved boost converter operating in discontinuous current mode. Thus, it is possible to mitigate the partial shading effects on photovoltaic arrays, also reducing size of passive elements and providing fast transient response. Experimental results on a PV system using a digital signal processor are presented to validate the proposed approach.

Published: July 2018

Este trabalho apresenta alguns resultados da mo- delagem e projeto dos controladores de um sistema de geração fotovoltaico de 30 kWp conectado à rede elétrica do Campus da Universidade Federal de Juiz de Fora. O conversor de interface é interligado a rede elétrica usando somente as indutâncias de dispersão de um banco de transformadores monofásicos como filtro passivo. O algoritmo de controle foi desenvolvido no sistema de coordenadas síncrono (dq0). Dois controladores proporcional–integral (PI– SRF) idênticos foram projetados para regular as correntes sintetizadas em cada coordenada. Será mostrado que o controlador PI–SRF pode ter seu desempenho reduzido quando correntes distorcidas são drenadas pelo trans- formador de conexão. Para contornar o problema anterior será projetado um controlador repetitivo (RC) para ser conectado em paralelo com o PI–SRF. O desempenho do controlador híbrido (PI–SRF + RC) é testado em regime permanente e transitório para variações na potência convertida nos painéis fotovoltaicos. Resultados experimentais são apresentados para validar o projeto e o desempenho do controlador híbrido proposto.
