Description
Summary:It presented the investigation on the reverse recovery of ABB HiPak 6 500 V/750 A IGBT module. For the first time, the forward recovery and the reverse recovery of diode and its anti-parallel connected IGBT were researched as a function of di/dt, and the impact on IGBT module was analyzed. It is confirmed that di/dt plays a critical role in the reverse recovery process, where damage can occur both to IGBT and diode chips at excessive di/dt, leading to possible subsequent short circuit failure between phase-legs of the converter. The importance of an optimised match between IGBT and gate driver to ensure safe operation and full exploitation of HiPak robustness is highlighted.
