The 1700V/400A hybrid module is consisted of Si-IGBTs and SiC-SBDs mounted in a general 2-in-1 package. Because the reverse recovery current of SiC-SBD is very small to be a unipolar device, reverse recovery and turn-on losses at 400A on the hybrid module are 83% and 38% lower than that of the conventional all-Si module, respectively. Therefore there is a further advantage of hybrid module at high-frequency operation. Radiation noise on hybrid module becomes higher with increasing collector current, but the peak value of the noise from hybrid module is almost the same as the all-Si module if the collector current is less than 300A. In AC690V PWM inverter, the total power dissipation of hybrid module is 8% lower at 1 kHz and 29% lower at 10 kHz compared to the all-Si module. Therefore the 1700V hybrid module is useful as a power module for an AC690V high-efficiency inverter system such as wind power generation system and high-voltage solar power generation system. This paper reports about the static and dynamic characteristics and the radiation noise measurement results on the 400A/1700V hybrid module.
