A Review on IGBT Module Failure Modes and Lifetime Testing

This article focuses on failure modes and lifetime testing of IGBT modules being one of the most vulnerable components in power electronic converters. IGBT modules have already located themselves in the heart of many critical applications, such as automotive, aerospace, transportation, and energy. They are required to work under harsh operational and environmental conditions for extended target lifetime that may reach 30 to 40 years in some applications. Therefore, addressing the reliability of IGBT modules is of paramount importance. The paper provides a comprehensive review on IGBT modules dominant failure modes, and long-term reliability. A detailed discussion on accelerated testing, and lifetime and degradation characterization considering thermo-mechanical stress is also presented in details.

本文聚焦于绝缘栅双极型晶体管（IGBT）模块的失效模式和寿命测试，IGBT模块是电力电子变换器中最易受损的部件之一。IGBT模块已经位于许多关键应用的核心位置，例如汽车、航空航天、交通运输和能源领域。它们需要在恶劣的运行和环境条件下工作，以达到某些应用中可能长达30到40年的预期使用寿命。因此，解决IGBT模块的可靠性问题至关重要。本文对IGBT模块的主要失效模式以及长期可靠性进行了全面综述。还详细介绍了加速测试以及考虑热 - 机械应力的寿命和退化特性。
