The Mechanism Analysis of IGBT Module Invalidation

摘要

The main purpose of this paper is to make a brief introduction of the applicable scope and the testing condition of IGBT module, to analyze the various reason causing IGBT module to be invalid which mainly involves drive part trouble, excessive heat, mechanical hurts, over voltage, over current and inductance that exists in the leads of circuit, and to make a general summary of the cautions which should be paid much attention to preventing IGBT module from being invalidated.
