Development of an Accurate Simulation Platform for Electric Vehicle Drive Inverters Considering Parasitic Parameters

In order to guide the selection of power components,assess the new technologies such as low-inductive film capacitors and laminated bus bar,and in the end realize the high power density and reliability for electrical vehicle inverters,an accurate simulation platform based on Matlab/Simulink has been developed.Parameters of the simulation platform strictly accord with the practical working conditions,even parasitic existing in components and connections are also considered.This paper introduces the switching mechanism and the distribution of circuit parasitic.The system modeling and parameters confirmation of the simulation platform are presented.The experimental results are shown to verify the effectiveness of the simulation platform.
