Abstract

As generally recognized, for the conventional power-factor-correction (PFC) boost converter operating in the continuous current mode (CCM), most of power dissipation comes from the reverse recovery current of the boost diode. Consequently, a simple zero-current-switching (ZCS) circuit, based on a passive circuit without any complicated switch control, is presented herein and applied to the boost diode of the PFC boost converter operating in CCM, so as to increase the total efficiency as well as to reduce the electromagnetic interference (EMI). Some simulation and experimental results are provided to verify the effectiveness of the proposed soft-switching topology.
