摘要：

A　novel　zero-voltage　and　zero-current　switching　(ZVZCS)　Full-bridge　converter　is　proposed　using　Asymmetric　Phase-shifted　PWM　Control,　Current　in　primary　winding　during　the　freewheeling　period　is　reduced　to　zero　by　adding　a　blocking　capacitor　and　a　saturable　inductor＇　realizing　ZCS　turn-on　and　ZVS　turn-off　for　chopping-leg　switches　as　well　as　ZCS　turn-on　and　turn-off　for　lagging-leg　switches.　The　control　method　is　easy　digital　realization,　overcomes　control　precision　and　flexibility　of　the　traditional　phase-shifting　control　special　chip.　The　operation　processes　and　characteristics　of　the　converter　are　analyzed,　and　a　prototype　is　built.　Experimental　results　verify　the　proposed　DC-DC　converter　with　low　freewheeling　energy,　low　switching　loss　and　high　efficiency.　©　Haijun　et　al.　Peng.
