Modeling Technologies for Power Electronics Integrated System

Power electronics system integration is a hybrid and complex work which involves several subjects such as material, mechanics, chemistry, informatics and so on. It can realize high power density, high efficiency, high reliability, harmony with environment and low cost for power electronics system. The modeling of power electronics integrated system is analyzed from three layers： switching and component cell layer, standardized power electronics module layer and system layer. The module - layer modeling includes establishing electrical, switching, thermal, thermodynamics and integrated model. The goal of the system - layer modeling is to study the steady, dynamic and transient functions and give the structure optimization strategies of the power electronics integrated system. The research orientation in the future is also discussed.
