Research on A Hybrid Integrated Three-phase Power Electronic Module

This paper describes the system configuration and the module physical structure of the 40kW hybrid inte-grated power electronics module applied to t hree-phase motor driver.According to the different application situation of th e motor driver,V/f control and field oriented control based on digital control are realized on the module.From the experimental result,we present a conclusion that the integrated module has characteristics of high power density,low volum e and flexibility for application. And the module proves that idea about power e lectronic integration is feasible.
