摘　　要：为了研究IGBT模块的开关瞬态特性,搭建一套基于LabVIEW的IGBT模块开关特性测试系统。对IGBT模块开关瞬态过程中的电压过冲进行了机理分析,并运用Saber仿真软件搭建双脉冲测试电路,仿真结果表明:电压过冲主要取决于测试回路中的杂散电感大小。测试电路经杂散电感优化后,通过搭建的IGBT模块开关特性测试系统进行验证,过冲电压同比减少约85%,对于IGBT模块的测试有一定的指导意义。In order to study the switching transient characteristics of IGBT module,a test system of IGBT module switching characteristics based on LabVIEW was built.The mechanism of voltage overshoot in IGBT module switch transient process was analyzed,and the double-pulse test circuit was built by Saber simulation software.The simulation results show that voltage overshoot mainly depends on the size of stray inductance in the test circuit.After the test circuit is optimized by stray inductance,it is verified by the IGBT module switching characteristic test system built,and the overshoot voltage is reduced by about 85%compared with that of the previous year,which has certain guiding significance for the test of IGBT module.
