Yan-Fei Liu




Yan-Fei Liu (Senior Member IEEE 1997, Fellow IEEE 2013) received his B.SC and M.Sc degrees from the Department of Electrical Engineering, Zhejiang University, China, and Ph.D degree from Queen's University, Canada, in 1994, all from Department of Electrical Engineering.

Dr. Liu has been on the Faculty at Queen's University since 1999 and currently holds the position of Professor of the Department of Electrical and Computer Engineering. He is a past Coordinator of Graduate Studies in the department. From 1994 to 1999, he was a technical advisor with Advanced Power System division of Astec (formerly Nortel Networks), where his was responsible for high quality design, new products and technology development. Dr. Liu and his research team have been conducting advanced research in the area of power electronics, including digital control technologies for DC-DC switching converters and AC-DC switching converters with power factor correction. Additional research has been conducted in EMI filter design methodologies for switching converters, technologies for high switching frequency low switching loss converters, and modeling and analysis of core loss and copper loss for high frequency planar magnetics. Dr. Liu and his team are also researching topologies and control for VRM (Voltage Regulator Modules) for CPU applications, and large signal modeling of switching converters.

He and his students have published over 170 papers in IEEE conferences and journals. Dr. Liu is also the inventor of 19 US patents and the inventor of three additional US patent applications. View Dr. Liu's publications.

Dr. Liu is the winner of the "Premiere's Research Excellent Award" (PREA) in 2001, and teaching award (in 2000, 2008, 2009, 2011, 2012, 2014); both at Queen's University. At Nortel, he was awarded the "1997 Award in Excellence in Technology." He is currently a member of the Professional Engineers of Ontario and an Associate Editor for IEEE Transactions on Power Electronics, as well as guest editor in chief for TPEL Special issue of Power Supply on Chip. He was a technical program co-chair for ECCE 2011. He also serves as a chair the IEEE Power Electrical Society Technical Committee on Power Conversion Systems and Components.

Dr. Liu is the principal contributor for two IEEE standards, IEEE Std 1515-2000, "IEEE Recommended Practice for Electronic Power Subsystems: Parameter Definitions, Test Conditions, and Test Methods", and IEEE Std 1573-2003, "Recommended Practice for Electronic Power Subsystems: Parameters, Interfaces, Elements, and Performance".
