Fully Soft Switched Bridgeless Buck Power Factor Correction Converter
In this paper, a bridgeless buck PFC structure is presented. To Fulfill soft switching for the main switches an auxiliary circuitry is utilized. The main switches of the proposed converter operate under ZVS condition and the auxiliary switch operate under ZCS condition. The proposed topology operates at Discontinuous conduction mode (DCM) leading to intrinsic PFC capability. A $120 \mathrm{~W}, 100 \mathrm{kHz}$ prototype is designed and simulated to validate theoretical analysis using PSIM software. The results show ${9 7 \%}$ efficiency and fully soft switching operation.
