Overview

About

Dr. Li received the Bachelor degree from Tianjin University, China, in 2002, and PhD degree from the School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore, in 2006. In 2005, Dr. Li was a Visiting Scholar with Aalborg University, Denmark. From 2006 to 2007, he was a Postdoctoral Research Fellow in the Department of Electrical and Computer Engineering, Ryerson University, Canada. Dr. Li also worked at Rockwell Automation Canada as a R&D Engineer, before he joined University of Alberta in 2007.


Dr Li is a registered professional engineer in the Province of Alberta. He serves in the Sustainable Energy Technical Committee of IEEE Power Electronics Society and Industrial Power Converters Technical Committee of IEEE Industry Application Society. He is an Associate Editor for IEEE Transactions on Power Electronics and IEEE Transactions on Industrial Electronics, and IEEE Journal of Emerging and Selected Topics in Power Electronics. Dr. Li received the 2013 Richard M. Bass Outstanding Young Power Electronics Engineer Award from IEEE Power Electronics Society.


Research

Research Interests

Power electronic technology plays a vital role in today’s energy systems in terms of efficient energy conversion, integration of dispersed energy resources, electric vehicles, etc. My research areas mainly involve power electronics and their applications in renewable energy, distributed generation (DG), microgrid, electric vehicles, electric motor drives, and custom power devices (for power quality improvement). The research interests of my group include power converter topologies, pulse-width-modulation (PWM) techniques, modeling and digital control of power electronics, grid synchronization techniques, etc.


Current Research

Grid integration of renewable energy systems (PV, wind) and energy storage systems.

Modeling, control and energy management of microgrid and active/smart distribution systems.

Ancillary services through grid-interfacing power converters.

High power converters and industrial drives.
