A Study On Synchronous Rectification Of Push-Pull Converter For Efficiency Improvement

효율개선을 위한 Push-Pull Converter의 동기정류에 관한 연구

Single winding self driven synchronous rectification(SWSDSR) scheme is based on an additional winding in the power transformer (auxiliary winding). It allows for maintaining the synchronous rectifiers on even when the voltage in the transformer is zero, which is impossible to do in traditional self-driven approaches. Its technique is verified to improve the efficiency by experiment. In this paper, there are compared self driven synchronous rectification(SDSR) with SWSDSR about the efficiency
