abstract: The field of power electronics advances through a number of different innovations, ranging from new and better semiconductors (e.g. power MOSFET, insulated gate bipolar transistor, gallium nitride, silicon carbide) to improved passive components enabled through material science breakthroughs. Moreover, through improved integration and packaging, higher performance and more complex circuits can be implemented. Thanks to digital control and improved simulation tools, new circuit topologies that better utilize the active and passive devices can be implemented in practical designs.

abstract: This eighth book in the series of popular power electronics books authored/edited by Prof. Bimal K. Bose was released in June 2019 in the IEEE Press Series on Power Engineering. According to the author/editor, the idea for the book appeared after the publication of the special issue of Proceedings of the IEEE "Power Electronics in Smart Grid and Renewable Energy Systems" in November 2017. Prof. Bose managed to mobilize 19 outstanding specialists in the field of power electronics and energy systems from around the world, who presented current issues in the 12 chapters of the book. The authors of individual chapters systematically review the latest technologies and provide examples of applications to familiarize readers with problems and solutions of modern power electronics in renewable energy systems and intelligent networks. The excellent style of Prof. Bose is apparent as each chapter begins with a clear introduction and ends with a constructive conclusion. Moreover, each chapter contains an extensive list of publications and what should be emphasized among them, the most up to date positions. Also, a list of abbreviations, biographies of contributors, and an index are included. This book is a valuable tool for graduate researchers, practicing engineers, and scientists working in the areas of renewable and distributed energy systems. It provides the needed technical background for each subject. Therefore, it is also suitable for senior undergraduate and master's level students of electrical engineering and power system faculties interested in modern power electronic energy systems.

abstract: Increased switching frequency of power devices for power electronics allows for compact and lightweight circuit implementations for variety of applications, including power factor corrections, DC/DC converters, and motor drive inverters. In particular, recent advances in GaN/SiC devices have pushed the switching frequency into the MHz range, which requires soft switching operation to minimize switching losses caused by the increased frequency. To achieve accurate soft switching operation in the MHz range, wideband isolated current and/or voltage sensing with bandwidth of at least 10MHz is mandatory, but few existing solutions have such a wide bandwidth and the ones that do are expensive.

abstract: This paper presents the design and optimization of a single turn magnetic core inductor for a 6kV, 40Hz power electronics building block (PEBB) using 10kV SiC MOSFET modules. The inductor design begins with a comprehensive comparison between air core, single turn and multi turn magnetic core structures, and the single turn magnetic core structure is concluded to be the most suitable solution for the given specifications. The design process is then followed by an optimization of geometric dimensions and magnetics by a trade off among power loss, volume, and parasitic capacitance. To achieve high compactness by minimizing the electric field stress in the air, a grounded shielding layer is applied to surround the winding, and the high electric field space is filled with void free solid insulators. Major issues resulting from the shielded winding structure include extra loss on the shield, concentrated electric field at fringes, and induced grounding current. These problems have been addressed by shield conductivity selection, a proposed field grading termination, and a well designed damping circuit, respectively. Finally, the fabrication process of a prototype and the experimental performance are demonstrated.

abstract: As shown in our previous studies, geometrical field grading techniques such as stacked and protruding substrate designs cannot well mitigate high electric stress issue within power electronics modules. However, it was shown that a combination of protruding substrate design and applying a nonlinear field dependent conductivity layer could address the issue. Electric filed (E) simulations were carried out according to IEC 61287 1 for the partial discharge test measurement step, where a 50/60 Hz AC voltage was applied. However, dielectrics, including ceramic substrate and silicone gel, in power devices undergo high temperatures up to a few hundred degrees and frequencies up to 1 MHz. Thus, E values obtained with electrical parameters of the mentioned dielectrics for room temperature and under 50/60 Hz may not be valid for high temperatures and frequencies mentioned above. In this paper, we address this technical gap through developing a finite element method (FEM) E calculation model developed in COMSOL Multiphysics where E calculations are carried out for different temperatures up to 250degC and frequencies up to 1 MHz. Using the model, the influence of temperature and frequency on our proposed electric field mitigation technique mentioned above is evaluated.

abstract: This paper summarizes the fault mechanisms specifically for the overvoltage protection schemes in power electronic converters and the resulted power electronics enabled systems. A flexible and secure evaluation platform for overvoltage protection, has also been presented based on this conceptual mechanism. The proposed platform aims at testing the protection performance of distinctive overvoltage protection schemes. It would be applied to verify the effectiveness, identify potential strengths and weaknesses, and obtain the most critical protection response time to provide sufficient engineering insights for the designer. The operation principle and detailed design guideline have been presented first. The comprehensive component stress has been analyzed. An intensive set of LTSpice simulations have been conducted to show the validity of the proposed assessment approach.

abstract: Aluminum electrolytic capacitors used in power electronics converters are a major factor that reduce the reliability of these devices. To evaluate the lifetime and reliability of this type of capacitors, capacitor loss needs to be evaluated under the excitation conditions of power electronics converters. However, the capacitor loss data provided by manufacturers is always measured under sinusoidal excitation. The authors therefore proposed a capacitor loss evaluation method for arbitrary excitation waveforms found in power electronics converters. This method features a simple configuration, and the capacitor loss can be practically evaluated using a function generator without the need of a real power electronics converter. Therefore, the capacitor loss can be analyzed under different conditions, ranging from fundamental analysis to practical analysis, for instance, pulse width modulated (PWM) inverter excitation. In this study, the capacitor loss was evaluated using fundamental excitation and (PWM) inverter excitation. Moreover, the capacitor loss of four different type of capacitors was assessed. Under PWM inverter excitation, nonlinear loss behaviors were observed. Nonlinear loss characteristics could be expressed using a hysteresis curve in the Q V plane. It was found that the hysteresis curves changed when the rectangular excitation current had zero current phases and different duty ratios due to the voltage unbalance of the tunnel pit capacitance in the capacitor sheets.
