Chi-Seng LAM of University of Macau

With the proliferation and increased use of power electronic devices (nonlinear loads) and motor loadings, such as: converters, adjustable speed drives (ASDs), bulk rectifiers, power supplies, elevators, escalators, large air conditioning systems, etc., the power quality (PQ) problems become more and more serious, especially for lower power factor, harmonic current, unbalanced current, etc., which strongly affects the performance, efficiency and reliability of the grid. Active power filter is one of the effective solutions to solve the PQ problems, however, its initial and operational costs are relatively high due to its high DC-link operation voltage requirement. To relax this drawback, the combination of passive and active power filters to form a hybrid active power filter (HAPF) can provide a cost-effective solution for PQ compensation. In this talk, the topology and control strategy of the HAPF system developed by University of Macau will be presented and discussed, and its practical application case in Macao will be introduced.

Biography:

Chi-Seng Lam (S’04–M’12–SM’16) received the B.Sc., M.Sc. and Ph.D. degrees in electrical and electronics engineering from the University of Macau (UM), Macao, China, in 2003, 2006, and 2012, respectively. He completed 2019 Clare Hall Study Programme in University of Cambridge, Cambridge, UK in 2019.

From 2006 to 2009, he was an Electrical and Mechanical Engineer with UM. In 2009, he simultaneously worked as a Laboratory Technician with UM and started to pursue his Ph.D. degree, and completed it within three years. In 2013, he was a Post-Doctoral Fellow with The Hong Kong Polytechnic University, Hong Kong, China. He is currently an Associate Professor with the State Key Laboratory of Analog and Mixed-Signal VLSI & Institute of Microelectronics, UM and also with the Department of Electrical and Computer Engineering, UM. He has co-authored/edited 4 books and more than 90 technical journals and conference papers. He holds 4 U.S. patents and 2 Chinese patents. His research interests include integrated power electronics controllers, power management integrated circuits, power quality compensators, renewable energy, wireless power transfer.

Dr. Lam was a recipient of the IEEE PES Chapter Outstanding Engineer Award in 2016, the Macao Science and Technology Invention Award (2nd Class and 3rd Class) and the R&D Award for Postgraduates (Ph.D.) in 2018, 2014 and 2012, respectively, and the 3rd RIUPEEEC Merit Paper Award in 2005. He was the Chair of IEEE Macau CAS Chapter from 2017 to 2018. He is currently the Vice-Chair of IEEE Macau Section and the Chair of IEEE Macau IES Chapter. He served as a member of Organizing Committee or Technical Program Committee of several international conferences.
