Design And Control Of Hybrid Active Power Filters

Design and Control of Hybrid Active Power Filters

Advanced Controllers Design for Hybrid Active Power Filters

The book focuses on different advanced current control strategies of LC-coupling hybrid active power filter (LC-HAPF) and Thyristor controlled LC-coupling hybrid active power filter (TCLC-HAPF). Both topologies and their corresponding advanced current control strategies are introduced, with more weight placed on the current control strategies. A total of 9 advanced current control strategies are studied in details for both LC-HAPF and TCLC-HAPF. The comprehensive and systematic treatment of advanced current controller design is one of the major features of the book, which is particularly suitable for readers who are interested in learning the design and implementation of current controller design for HAPFs. The book can benefit researchers, engineers, undergraduate and postgraduate students in the fields of electrical and electronic engineering, power electronics, control strategy, etc.

Adaptive Hybrid Active Power Filters

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.
