Abstract:IGBT modules are core components of power electronic converters, and their reliability has gained significant attention. Among various reliability concerns, bond wire fatigue is a prominent issue. Bond wire fatigue can alter the electrical characteristics of IGBT modules, affecting the turn-off process of the IGBT. Consequently, it leads to changes in the collectoremitter voltage spike and the auxiliary emitter-emitter voltage spike during the turn-off process. The paper proposes the utilization of the K facto… Show more
