摘要

针对大功率IGBT短路保护技术，详细介绍了IGBT短路及其保护原理，通过不同工作电压下短路试验波形验证了IGBT短路时间与其工作电压密切相关，得出了IGBT工作电压越高短路时间越短的反比关系，最后通过短路试验数据拟合曲线分析证明了不同工作电压下IGBT的短路能量相同。

Abstract

In view of the high-power IGBT short-circuit protection technology, the IGBT short-circuit reason and protective principle was introduced. The short circuit time of IGBT was verified to be closely related to its working voltage by short circuit test waveforms under different working voltages. The inverse relationship between IGBT short circuit time and IGBT working voltage was obtained. It was proved by data fitting curve of short-circuit test that the short-circuit energy of IGBT was the same under different working voltages.
