The Next Generation 6.5kV IGBT

This paper introduces the next (7th) generation 6.5kV chip set, IGBT and FWDi, for high voltage IGBT (HVIGBT) modules.  New technologies for both the IGBT and FWD chips are adopted to increase the current rating while maintaining high robustness and package compatibility.  These technologies achieve successful turn off of 4400A at 4.4 times rated nominal current (IC(nom)) confirming that the rating of the new 6.5kV module can be increased to 1000A from the 750A rating of the conventional module while maintaining high robustness and operating margin.
