The Parametric Model and Simulation Analysis of IGBT
Abstract: In this paper, based on the analysis of the structure and work principle and characteristics of IGBT, the simplified model of IGBT by matlab/simulink is built. The problems of the IGBT failure are analyzed theoretically from the perspectives of IGBT failure factors and failure mechanism, re-spectively. According to simulation results, it was verified that IGBT is subjected to constant electric shocks due to work environment, etc., then, module internal bonding wire begins to creep and fatigue cracks occur, which eventually lead to failure. Thus, the model can be used to predict the lifetime of the IGBT.
