A　novel　current　driven　method　for　center-tapped　synchronous　rectifier　(SR)　is　proposed　in　this　paper.　Compared　with　the　previous　current　driven　synchronous　rectifier　(CDSR),　two　SRs　can　be　driven　with　only　one　current　transformer　by　using　the　proposed　CDSR.　The　new　CDSR　has　the　advantages　such　as　simple　structure,　low　power　loss　and　good　performance　and　so　on.　The　performance　of　the　proposed　circuit　is　verified　on　an　experimental　LLC　prototype　converter.　©　2010　IEEE.
