摘要
简述了大功率IGBT短路保护的类型,从IGBT器件本身的输出特性出发,分析了退饱和检测法在短路保护电路中的应用,指出了IGBT的短路承受能力。以CONCEPT公司的SCALE驱动器为例,通过桥臂直通和桥臂相间短路的实验,证实了IGBT退饱和检测法在大功率IGBT短路保护中的有效性,并且对两类短路保护的有效性进行了对比。
The types of high power IGBT short circuit protection was expounded. It analyzed the desaturationdetection in the application of short circuit protection circuit from the output characteristic of the IGBT device itselfand pointed out the short circuit ability of IGBT. The experiments of the arm shoot through and phase to phase shortcircuit with the CONCEPT of SCALE driver that confirm the effectiveness of desaturation detection in the high powerIGBT short circuit protection. The effectiveness of the two kinds of short circuit protection is compared also.
