abstract: This paper presents the comparison of various Carrier Overlapping Pulse Width Modulation (COPWM) Strategies for the chosen three phase Cascaded Multi Level Inverter (CMLI) Various new schemes adopting the constant switching frequency and also variable switching frequency multicarrier control freedom degree combination concepts are developed and simulated for the chosen three phase CMLI. The three phase CMLI, is controlled in this paper with Sinusoidal PWM (SPWM) reference along with Carrier Overlapping (CO) techniques and simulation is performed using MATLAB SIMULINK. The variation of fundamental RMS output voltage and total harmonic distortion is observed for various carrier overlapping techniques. Among the various equal amplitude carrier overlapping techniques such as COPWM 1, COPWM 2, COPWM 3, and COPWM 4, it is observed that COPWM 3 provides less Total Harmonic Distortion (THD) and COPWM 4 provides relatively higher RMS voltage. Among the various Variable Amplitude COPWM (VACOPWM) techniques such as VACOPWM 1, VACOPWM 2, VACOPWM 3, and VACOPWM 4, it is inferred that VACOPWM 3 provides less THD and VACOPWM 2 and VACOPWM 3 provide higher RMS voltage. It also found that VACOPWM strategies perform better than corresponding COPWM strategies.

abstract: The hysteresis current controller provides excellent dynamic performance, whereas the Proportional Integral controller provides instantaneous current control and wave shaping, fixed inverter switching frequency resulting in only known harmonics. A comparative study between Hysteresis current control and Proportional Integral (PI) current control using sinusoidal pulse width modulation (SPWM) techniques for a five level cascaded H bridge multilevel inverter is presented in this paper. A comparison has been made in terms of total harmonic distortion (THD) level at the three phase load current. The simulation study has been carried out with the help of MATLAB Simulink software and the performance of such controllers has been observed during load variations.

title: Investigations on Three Phase Five Level Cascaded type FCMLI
year: 2012

abstract: This work proposes a comparison study of cascaded H bridge multilevel inverter (CHBMLI) in which symmetrical and asymmetrical arrangement of five level and seven level H bridge inverters are compared in order to find an optimized output voltage quality with lower harmonic distortion. Several studies have been conducted on the three phase cascaded symmetrical multilevel inverter (MLI).However, there are few studies that actually discuss or evaluate the performance of three phase H bridge asymmetrical MLI. Here, three multicarrier pulse width modulation (PWM) techniques such as constant switching frequency, variable switching frequency and phase shifted PWM are proposed. MATLAB/SIMULINK software is used for simulation. The carried out simulation studies shows that an asymmetrical configuration provides high output voltage with very low total harmonic distortion (THD) using less switching devices.

abstract: This paper presents the comparative study of three phase twenty five level diode clamped and cascaded H bridge multilevel inverters. The comparison is made in respect of requirement of devices, quality of output voltage and reduction of total harmonic distortion at the multilevel inverter terminals. In this work multicarrier sinusoidal pulse modulation control methods of Phase disposition (PD PWM) phase opposition disposition (PODPWM) and Alternative Phase Opposition Disposition (APOD PWM) pulse width modulation control strategies are applied for both diode clamped and cascaded H bridge multilevel inverters and compared its total harmonic distortion. The performance of both diode and cascaded H bridge multilevel inverters is investigated and compared. Based on simulation results it is observed that the output voltage of the cascaded H bridge multilevel inverters is better as compared to the diode clamped multilevel inverter. The proposed multilevel inverters are simulated using MATLAB/Simulink software.
