Abstract: This paper presents a bridgeless PFC boost converter for power supply and battery charging applications. Boost converter operating in CCM is widely used in low power factor corrector due of its simplicity and switching losses. The converter operates in both pulse-width-modulation (PWM) mode and resonant mode in each switching cycle, and use standard average current mode control. The performance of the proposed model is evaluated under varying input voltages and loads by simulating the circuit in MATLAB/Simulink environment.

Keywords: AC-DC converters, PFC, resonant converters, soft-switching, ZCS, ZVS.
