초록

In this paper, we propose a three-phase soft-switching PWM-PFC converter and describe the circuit operations and the experimental results. The proposed converter is constructed by using a resonant network in parallel with the main switch of the conventional PWM converter. A new PWM-PFC converter achieves including the auxiliary switches without increasing their voltage and current stress.
