Abstract

This paper presents a turn-on turn-off zero-current switching (ZCS) converter in a PFC boost application. The applied soft-commutation cell is capable of providing ZCS operation keeping the main switch current equal to the input current. Substituting the typical PWM cell found in classics power converter structures by the presented ZCS cell with three switches and taking to account the invariance principle, zero current switching of all active switches is achieved without additional current stress of the main switch. The operation and main properties of this converter are also included. Design guidelines with a design example are described and verified by simulation results.
