John Lam

Assistant Professor

Research Interests
  • High frequency power conversion for sustainable energy systems, power converter topologies, control techniques for power converters;
  • Power factor correlation techniques.

John Lam received the B.Sc. (Hons.) degree in Electrical Engineering and the B.A. degree in Economics from Queen’s University, Kingston, ON, Canada, in 2003. He received his M.Sc. and Ph.D. degrees in electrical engineering from Queen’s University in 2006 and 2010, respectively. From 2010-2012, he received the MITACS (Mathematics of Information Technology and Complex Systems) Elevate Postdoctoral Fellowship, where he worked on single-stage high power factor high frequency power inverters for energy-efficient lighting and sustainable energy applications. Dr. Lam is currently an Assistant Professor with the Department of Electrical Engineering and Computer Science, York University, Toronto. His research interests include high frequency power converters with soft-switching techniques, renewable energy applications, and advanced control techniques for high frequency converters. He is the Principal Investigator of the Advanced Power Electronics Laboratory for Sustainable Energy Research at York University.

He is an IEEE Senior Member and is an Associate Editor of the IEEE Transactions on Power Electronics. He has served as a Technical Session Chair in several conferences supported by the IEEE Power Electronics Society and the IEEE Industry Applications Society
