Abstract :
In the paper, the soft-switched technique is used in the AC/DC rectifier. A new voltage-fed AC/DC high power factor rectifier with bridge-mode parallel resonant-DC-link is proposed and ZVZC switching can be realized for bridge devices. The two kinds of operating states for the rectifying and inverting are analyzed in normalization with the phase-plane method and the phase-plane figure is given. On this basis, the critical conditions which guarantee all switch devices to realize soft-switching, are discussed and the main parameter design is made. The results of simulations and experiments are presented
