무손실 스너버적용 소프트 스위칭 Single Stage AC-DC Full Bridge Boost 캔버터
Soft Switching Single Stage AC-DC Full Bridge Boost Converter Using Non-Dissipative Snubber Circuits
초록
A new soft switching single stage AC-DC full bridge boost converter with unit input power factor and isolated output is presented. Due to using of the non-dissipative snubber in the primary side, a single stage high-power factor isolated full bridge boost converter has a significant reduction of switching losses in main switching devices and output rectifiers of the primary and secondary side, respectively. The non-dissipative snubber adopted in this study is consisted of a snubber capacitor C. and a snubber inductor
