Abstract :
We have developed a rectifier which consists of a boost-chopper with zero-voltage switching and a full-bridge zero-voltage switching converter using bipolar-mode static induction transistors (B-SITs). A 5 kW-output experimental model achieved the following: high efficiency of 93%, high power density of 0.28 W/cm3, and its harmonic currents satisfy IEC standards
