A new soft switching single stage AC-DC full bridge boost converter with unit input power factor and isolated output is presented in this paper Due to the use of a non-dissipative snubber on the primary side, a single stage high-power factor isolated full bridge boost converter has a significant reduction of switching losses in the main switching devices, The non-dissipative snubber adopted in this study consists of a snubber capacitor Cr. a snubber inductor Lr, a fast recovery snubber diode Dr, and a commutation diode Dr, This paper presents the complete operating prin챠ples, theoretical analysis and experimental results.
