摘要

基于三维有限元电热机械模拟(COMSOL)和二维多单元模拟(Sentaurus TCAD)，我们探讨了电源组件失效的主要老化现象(焊线脱落和焊点分层)对MOS门控电源器件(IGBT, VDMOS)电气特性的影响。分析了电特性变化，以期将其用于嵌入式电源组件的健康监测。

Exploring ageing effects on integrated power devices (I–V) for health monitoring

Based on 3D FEM electro thermo mechanical simulations (COMSOL) and 2D multi-cells simulation (Sentaurus TCAD), we explore the impact of main ageing phenomena (bonding wire lift off and solder joint delamination) at the origin of power assembly failures, on the electrical characteristics of MOS gated power devices (IGBT, VDMOS). Electrical characteristics variations are analyzed with a view to using them for health monitoring of embedded power assemblies.
