Full-bridge　zero-voltage-switched　PWM　converter　combines　advantages　of　the　PWM　control　technique　and　ZVS　resonant　technique.　However,　full　ZVS　is　achieved　only　under　large　load　current　because　resonant　tank　of　this　circuit　is　made　up　of　the　parasitic　capacitance　of　the　power　semiconductors　and　the　leakage　inductor　of　the　transformer　primary.　Two　saturable　inductors　as　magnetic　switch　are　added　to　secondary　coil,　so　output　filter　inductor　is　always　reflected　to　primary　and　assists　resonant　transition.　Full　ZVS　is　achieved　under　lower　load　current.　The　above-mentioned　investigated　results　is　validated　by　the　computerized　simulation　and　hardware　circuit　experimentation.
