This paper presents the enhanced characteristics of a newly developed low-loss and low-noise 1200-V insulated gate bipolar transistor (IGBT) module. In order to realize low-noise emission, it is necessary not only to improve the reverse recovery characteristics of the free wheeling diode (FWD) but also to reduce the low-current turn-on dIC/dt of the IGBT. The new IGBTs with high turn-on dIC /dt controllability and low turn-on power dissipation have been successfully developed by the reduction of Miller capacitance resulting from an optimization of the surface. The 1200-V 450-A IGBT module utilizing the new IGBT and optimized FWD chips has been able to realize 30% reduction of the switching power dissipation when compared to the conventional IGBT module under the operating condition to set the same noise emission level
