Yan-Fei Liu

Yan-Fei Liu is a Professor in the Department of Electrical and Computer Engineering at Queen’s University, Canada, with a focus on power electronics and high-efficiency power conversion systems. He holds positions as Vice President of Technical Operations for the IEEE Power Electronics Society and Editor of the IEEE Journal of Emerging and Selected Topics of Power Electronics (JESTPE).

Dr. Liu’s education includes a B.Sc. and M.Sc. from Zhejiang University (China, 1984-1987) and a Ph.D. from Queen’s University (1994). He has authored over 280 technical papers, holds 61 U.S. patents, and contributed to IEEE standards. His research emphasizes GaN/SiC devices, high-efficiency converters, digital control for resonant systems, and EV power solutions.

Key research areas include:
- High-power-density DC-DC bus converters for data centers
- Multi-phase interleaved LLC resonant converters
- Digital control for current sharing and fast dynamic response
- GaN-based AC-DC converters for USB PD applications
- On-board EV DC-DC converters
- Thermal management innovations like IMLC and PSI2 technologies

His 15 most recent articles focus on advanced converter topologies (e.g., LLC, LCLC), digital control strategies, thermal packaging, and energy storage systems. Awards include IEEE Fellow (2013) and CAE Fellow (2018), alongside industry recognitions like Nortel’s Excellence Award (1997).

Supervision includes four postdoctoral fellows (Wenbo Liu, Xiang Yu, Bo Sheng, Yang Chen). His lab develops next-generation power systems with a focus on miniaturization, efficiency, and sustainable energy applications.
