Traditional　half　bridge　dual　buck　inverter　(DBI)　has　a　low　power　density　due　to　the　employing　of　two　large　input　capacitances　and　two　discrete　output　inductors.　Magnetic　integration　is　an　effective　method　to　enhance　power　density.　However,　unexpected　circulating　current　may　be　induced　by　adopting　conventional　magnetic　integration　scheme.　This　paper　proposes　a　novel　magnetic　integrated　DBI　inverter,　which　can　eliminate　circulating　current　by　using　a　partly　coupled　inductors　with　non-dotted　ends　connected.　The　power　density　can　be　elevated　effectively　by　eliminating　two　large　input　capacitances　and　coupling　two　discrete　inductors　simultaneously.　In　addition,　the　modified　model　predictive　control　(MPC)　scheme　has　been　applied　to　obtain　more　outstanding　performance　in　zero-crossing　point　compared　with　traditional　voltage-current　dual　loop　PI　control.　The　generating　principle　of　circulating　current　and　operating　principle　of　proposed　inverter　have　been　analyzed　in　detail.　Finally,　simulation　and　experiment　results　demonstrate　the　feasibility　of　the　proposed　inverter.
