The process of IGBT switching was analyzed, and then a new gate driver with multi-protections was designed. The contractive researches between new gate driver and common gate driver and researches on module short circuit were also done. Result indicates that the new gate driver had better driving characteristics and protection performance than common gate driver with the response rate of short through increasing five times and short-circuits power consumption reducing by seventy-one percent.
