短路能力是衡量IGBT(绝缘双极型晶体管)模块性能的重要指标,短路保护功能在很大程度上决定了变流器的可靠性和失效率。主要介绍了IGBT模块短路保护电路的必要性和3种短路测试方法。
Short circuit capability is a measure of IGBT (Insulated Bipolar Transistor) module performance an important indicator of short-circuit protection to a large extent determines the reliability and failure rate of the converter. The necessity of IGBT module short circuit protection circuit and three kinds of short circuit test methods are mainly introduced.
