Construction and Application of Electro-Thermal Co-simulation Platform

Abstract

This paper introduces the construction and application of the electro-thermal co-simulation platform. Based on the finite element method, we first established a device-level simulation model of IGBT and diode with dynamic characteristics; at the same time, we extracted the corresponding network model through CFD simulation calculation of the transient operating conditions of the IGBT device; then, using 1200V 600A IGBT as an example to build a complete electro-thermal co-simulation platform; finally, the simulation data of the electro-thermal co-simulation platform and the test data of the developed 1200V 600A device are tested and verified under the same working conditions.
