It　is　difficult　to　take　into　account　the　second-order　current　ripple,　common-mode　(CM)　current,　and　efficiency　of　the　converter　in　the　application　of　vehicle-to-grid　(V2G).　To　address　this　issue,　an　asymmetric　full-bridge　dc-ac　converter　is　presented　in　this　article,　which　can　realize　single-stage　conversion　by　multiplexing　switches　and　suppress　CM　current　from　the　topology　principle.　A　dual-target　control　strategy　for　this　converter　is　proposed　to　implement　bidirectional　power　transmission　and　power　decoupling.　Through　power　decoupling　the　dc　port　secondary　ripple　is　transferred　to　the　dc　bus　capacitor　voltage.　Besides,　the　circuit　topology,　control　strategy,　operation　principle,　high-frequency　switching　process,　key　circuit　parameters　design,　and　losses　are　analyzed　theoretically.　A　250　W　prototype　is　built　to　verify　the　theoretical　analysis.　Based　on　the　experimental　results,　the　efficiency　is　92.21%　while　the　secondary　ripple　current　of　dc　port　is　less　than　3%　and　the　common　mode　leakage　current　is　almost　zero　at　rated　power.　Finally,　the　proposed　converter　system　is　compared　with　other　research　solutions,　and　the　experimental　results　indicate　that　the　converter　system　has　the　optimal　comprehensive　performance.　©　2013　IEEE.
