Prof. Wong Man Chung from the University of Macau (UM) Department of Electrical and Computer Engineering (ECE), and Dr. Lam Chi Seng from the State Key Laboratory of Analog and Mixed-Signal VLSI (AMS-VLSI Lab), published a book entitled “Design and Control of Hybrid Active Power Filters” via Springer, the world’s largest publisher in the fields of medicine, science and technology, in January 2014. It is UM’s first published book on power electronics. It has received support from the Science and Technology Development Fund of Macao SAR and UM’s Research Committee. The relevant research projects were conducted in the Power Electronics Laboratory of the Faculty of Science and Technology.

The book not only analyses the structure, compensation performances and system design of the latest hybrid active power filter, but also proposes a strategy for building a low-cost and low-loss new-generation power quality compensator. The research results contained in this book represent a breakthrough in the functions of the modern hybrid active power filter, allowing the filter to compensate both harmonic current and dynamic reactive power at lower costs. The book also proposes a novel nonlinear current injection pulse width modulation control strategy, and presents a novel adaptive dc-link voltage control method to minimise the filter system switching loss and switching noise. The traditional method requires additional soft-switching circuit to reduce switching loss, but the proposed control method can achieve the same switching loss reduction at no additional costs. Applications for patents have been filed for this innovative control algorithm in both the United States and China. The research results in this book have led to publications in the world’s top power electronics journals, including the IEEE Transactions on Industrial Electronics (Impact Factor: 5.165) and the IEEE Transactions on Power Electronics (Impact Factor: 4.080), as well as one Chinese invention patent. The control methods proposed in this book can be applied to develop mixed-signal integrated power electronic controller IC, which can effectively improve the performance of power electronics systems.

Since its founding in 1999, the Power Electronics Laboratory has published 26 journal papers (16 of which in SCI-indexed journals), 71 international conference, and 1 book. The publication of this book through Springer represents a milestone in the history of the Power Electronics Laboratory because it is the first book published by the lab since its founding and shows international recognition of UM’s research capacity.
