Abstract :
A simple soft-switched single-phase AC to DC converter, involving only two switching devices is proposed. The system yields less EMI, because of soft switching, and the input line-current becomes quasi-sinusoid with almost unity power-factor. As this system utilizes high-frequency switching, the size of the input filter becomes quite small
