HIGH-POWER CONVERTERS AND AC DRIVES

This book presents the latest cutting-edge technology in high-power converters and medium voltage drives, and provides a complete analysis of various converter topologies, modulation techniques, practical drive configurations, and advanced control schemes. Supplemented with more than 250 illustrations, the author illustrates key concepts with simulations and experiments. Practical problems, along with accompanying solutions, are presented to help you tackle real-world issues.

Dr. Bin Wu received his PhD in Electrical and Computer Engineering, at the University of Toronto in 1993. He holds 5 US patents in high-power converters and ac drives. Dr Wu has published 90 papers in power electronics and ac drives, received a total research funding of $2.8 milion dollars from the government and private sector, and has received various awards at national, provincial and institutional levels, including the Gold Metal of the Governor General of Canada, NSERC Synergy Award for Innovation, Premier Research Excellence Award, Ryerson Sarwan Sahota Distinguished Scholar Award and Ryerson Research Chair Award. Dr. Wu has also developed a number of power electronics based products for various companies, including Rockwell Automation (Allen- Bradley), Honeywell Aerospace, Lumacell Inc, Allanson International Inc and Industrial Lighting & Electric. He has produced over 70 technical reports for the above-mentioned companies. He was also the founder of LEDAR (Laboratory for Electric Drive Research and Applications) – the best of its kind in Canadian Universities.
