A wide soft switching range Power factor correction Converter

In this paper, a totem-pole power factor correction converter with low THD, high efficiency and wide soft switching range in the entire power grid voltage cycle, is presented. The converter has a proper efficiency at high frequencies due to the energy recovering of the snubber capacitor and the switches parasitic capacitor. Due to the DCM operation, this converter has an inherent power factor correction and does not need a control circuit to form the input current. Also, due to its structure, the main switches are pulsed simultaneously regardless of the input voltage positive or negative half cycle, which simplifies the control circuit. In this paper, the principles of circuit operation and analysis of the proposed converter are presented and verified by simulation results.
