Design and Control of Hybrid Active Power Filters presents an overview of the current quality problems and their compensators. To get a balance between the system cost and performance, hybrid active power filters (HAPFs) are valuable. The book presents the coverage of resonance phenomena prevention capability, filtering performance and system robustness analysis of HAPF; nonlinear inverter current slope characteristics and their linear operation region requirement analysis of the hysteresis PWM for the HAPF; minimum inverter capacity design procedure of HAPF, adaptive dc-link voltage controller for the HAPF and the real design example of a 220V 10kVA HAPF, in which the system performance analysis method, minimum dc voltage deduction concept and adaptive dc voltage idea can be further extended into the other active compensators, such as APF, static synchronous compensator STATCOM, etc. This book will benefit researchers, graduate students, and electrical power engineers in thefield of power-quality compensation.Dr. Chi-Seng Lam and Dr. Man-Chung Wong are both from the University of Macau, Macao, China.

This book introduces advanced thyristor-based shunt hybrid active power filters (HAPFs) for power quality improvement in power grids, which are characterized by a low dc-link operating voltage and a wide compensation range. This means they can overcome the high dc-link voltage requirement of conventional active power filters and the narrow compensation range problem of LC-coupling hybrid active power filters. Consisting of 10 chapters, the book discusses the principle, design, control and hardware implementation of thyristor-based hybrid active power filters. It covers 1) V-I characteristics, cost analysis, power loss and reliability studies of different power filters; 2) mitigation of the harmonic injection technique for thyristor-controlled parts; 3) nonlinear pulse width modulation (PWM) control; 4) parameter design methods; 5) minimum inverter capacity design; 6) adaptive dc-link voltage control; 7) unbalanced control strategy; 8) selective compensation techniques; and 9) the hardware prototype design of thyristor-based HAPFs, verified by simulation and experimental results. It enables readers to gain an understanding of the basic power electronics techniques applied in power systems as well as the advanced techniques for controlling, implementing and designing advanced thyristor-based HAPFs.

This book offers a brief review of and investigations into the power quality problem in the new technology of co-phase high-speed traction power supplies, which benefits for higher locomotive speed. In addition, it presents detailed design procedures and discusses the chief concerns in connection with a newly proposed solution: compensation in co-phase traction power using a co-phase railway hybrid power quality conditioner (Railway HPQC). Further, it provides essential information on the modeling of power quality in co-phase, high-speed traction power supplies, and on power quality compensation algorithm derivations. Lastly, it delineates the design of railway HPQC and analyzes the effect of different parameters on its performance to accommodate different priorities. All design is supported by simulations and the results of experimental verification.

This book provides the potential advantages of adaptive impedance converters in different applications, such as power quality compensations, AC/DC microgrids, co-phase railway traction supply systems, and underwater electroacoustic transduction systems. In these applications, the adaptive impedance converter models, topologies, and control methods are introduced in this book.Adaptive impedance converters are designed to transform the impedance of an electronic system to optimize its performance. The adaptive impedance converter is typically implemented using passive and active electronic components to achieve impedance transformation. The main advantage of adaptive impedance converters is their ability to dynamically adjust the impedance to optimize system performance, which can help improve signal quality, reduce interference, and minimize power losses. Whether it is passive based adaptive impedance converters and active adaptive impedance, they both can applied into different applications including distribution system, renewable energy integration, AC/DC microgrids, traction supply system, and power amplifiers to achieve good performances and ensure efficient power transfer. The passive-based adaptive impedance converters can effectively reduce the converter rating and power loss, maintaining a large operational range. The active adaptive impedance can change its impedance varying with frequency, load conditions, or other factors to match the impedance of the source or load, providing efficient power transfer and minimizing signal reflections.The target audience of this book is the research scholars (including master’s and Ph.D. students) in power electronics and electrical engineer.
