Abstract :
A novel ZVZCS-full-bridge converter compounding the three-phase power factor corrector in a single-stage is presented. As the pseudo-phase-shifting control (PPSC) mode, the voltage on the dc link is restrained, not more than 800 V. Computer simulation and experiment results of the prototype show that the zero switching, power factor correcting and the output regulating are completed simultaneously in use of one converter
