摘要 绝缘栅双极型晶体管(IGBT)是电力电子系统实现电能变换与控制的核心组件之一。然而,工业界反馈的数据表明,应用于高可靠性场合的IGBT模块可靠性并不高,其热疲劳失效将会导致整个系统的非计划停机。对IGBT模块的预期使用寿命进行评估,将有助于指导电力电子装置的定期维修,降低经济损失。相关研究表明,IGBT模块的失效和温度关系密切,因此该文从热特性角度阐述IGBT模块的寿命评估。具体涉及热疲劳失效机理、热网络的建立与应用、热参数的辨识与监测、结温的估算及用于寿命预测的失效物理和解析模型五个方面。最后总结了现有研究存在的难点,并对IGBT模块的寿命评估研究发展方向进行了展望。

Abstract:Insulated gate bipolar transistor (IGBT) is one of the core components in the power electronics system, which realizes the energy conversion and management. However, industrial survey shows that the reliability of IGBT modules in high-reliability applications is not high, and the thermal fatigue failure of IGBT modules will lead to the unplanned downtime of the entire system. Lifetime evaluation of IGBT modules will help guide the scheduled maintenance of power electronic equipment and reduce economic costs. Relevant studies indicate that the failure of IGBT modules is closely related to temperature. Thus, this paper reviewed the lifetime evaluation of IGBT modules from the perspective of thermal characteristics. Following five aspects were introduced: failure mechanism of thermal fatigue, establishment and application of thermal network, thermal parameter identification and monitoring, junction temperature estimation, and analytical and physical models for lifetime predication. Finally, the challenges of existing research were summarized, and the lifetime evaluation of IGBT modules was prospected.
