Abstract

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.

Highlights

According to field experience, power electronic converters are considered a weak link that has significant influence on overall electrical system reliability [1], [2]
According to motor drive manufacturers [10]–[12], drives may end up working in tough environments, which are impossible to know before leaving the factory; thereby qualification test conditions may not match field operation
IGBT modules are subjected to stresses higher than typical field conditions to accelerate wear-out failure modes [25]–[28]
