摘要: 随着电动汽车领域越来越多地使用绝缘栅极晶体管(IGBT)模块,在这些关乎乘员安全的场合,通常要求IGBT模块具有更高的可靠性。选取了典型的汽车级和工业级IGBT模块产品,分别进行了功率循环和温度循环试验,对比了2种模块的可靠性差异,结果表明,汽车级模块产品的功率循环寿命较工业级产品差,但是温度循环寿命明显优于工业级产品。

Abstract: The power semiconductor module is more and more widely used in human transportation field, like electric vehicle and high-speed train. These applications in which the personnel safety is seriously concerned usually require power modules with higher reliability. In this paper, the typical automotive and industrial grade insulated gate bipolar transistors (IGBT) were selected. Both the power cycling and thermal cycling tests were carried out to compare the reliability differences. The experimental results showed that the thermal cycling lifetime of automotive IGBTs was obviously better than that of industrial grade products. However, the power cycling lifetime of automotive IGBT was worse than that of the industrial grade product.

Key words: IGBT, power cycling, thermal cycling, reliability
