He is the President of China Power Supply Society and the Editor-in-Chief of the society’s English journal.  He is also a Vice President and the Secretary General of the CES Power Electronics Society.  He serves as a Vice Chair of the Chinese National Steering Committee for College Electric Power Engineering Education Programs as well.  His research interests include modeling, control, and design methods for power converters and electronified power systems, power quality control and utility applications of power electronics, and micro-grids for sustainable energy and distributed generation.

High resolution computing in both spatial and temporal sense on the components’ electric-thermal stress becomes more and more crucial for a comprehensive evaluation of the safety margin as well as an optimized design of a power electronic equipment.  However, there is always a conflict between high resolution/precision and computing speed/efficiency in general.  This presentation will introduce some of the specific techniques that have been developed recently to tackle this conflict and achieve efficient/fast computing while keeping high resolution/precision for the stresses on some of the key components in power electronic equipment such as power semiconductor devices and capacitors.
