Abstract :
In this paper, a novel prototype of a zero voltage soft-switching PWM three-phase AC/DC active power converter with a new transformer-assisted quasi-resonant tank DC link (TQRDCL) is presented for power factor correction, sinewave line current shaping and constant output DC voltage regulation. The instantaneous space voltage modulated sinewave line current synthesizing scheme of this high-power factor active rectifier with an instantaneous output DC power feedback loop is implemented by digital signal processor-based software and its related hardware. The simulation results of this soft-switched active rectifier are illustrated and discussed as compared with the other resonant DC link rectifiers and hard-switched active rectifier
