摘要

近年来，金属降解作为电力设备在主动循环条件下的失效机制受到越来越多的关注，即在重复脉冲电压/电流负载下[1,2]。电热模拟和热力学模拟对于理解这一机制是必不可少的。本文给出了一个专用测试结构的实验和仿真数据。一个合适的寿命模型必须超越简单的Coffin-Manson型模型，以捕捉重要的影响参数。

Modelling of metal degradation in power devices under active cycling conditions

Metal degradation has recently received increased attention as a failure mechanism in power devices under active cycling conditions, i.e. under repeated pulsed voltage/current loads [1, 2]. Both electro-thermal and thermo-mechanical simulation are indispensable for understanding this mechanisms. The paper presents experimental and simulation data for a dedicated test structure. A suitable lifetime model has to go beyond a simple Coffin-Manson type model to capture the essential influencing parameters.
