With　the　development　of　electric　vehicles　(EVs),　lithium-ion　batteries　have　two　rated　voltages:　400　and　800　V,　and　are　suitable　for　different　output　power　scenarios.　Considering　the　interoperability　of　public　wireless　power　transfer　(WPT)　facilities,　the　WPT　system　for　EVs　not　only　needs　to　be　compatible　with　the　battery　voltage　class　(BVC)　under　the　premise　of　meeting　the　corresponding　output　power　level,　but　also　needs　to　take　into　account　different　coupling　structures,　namely　unipolar　(Q)　and　bipolar　(DD)　coils.　Under　the　background　of　the　interoperability　of　the　above-mentioned　BVC　and　coupling　structures,　an　integrated　dual-decoupled　transmitter　is　proposed.　First,　finite　element　analysis　and　optimization　were　carried　out　for　the　proposed　coupling　structure.　While　obtaining　the　optimal　coil　parameters,　the　interoperability　performance　with　Q　and　DD　coils　was　also　achieved.　Then,　by　combining　circuit　topology,　four　different　output　modes　can　be　achieved,　which　are　used　to　adapt　to　the　BVCs　under　different　power　levels　and　different　coupling　structures.　A　downscaled　experimental　prototype　with　the　power　of　5.0-kW　was　established.　Under　the　premise　of　200　V　input　voltage,　the　efficient　transmission　of　200　and　400　V　output　of　Q　and　DD　coil　was　achieved.　The　dc–dc　efficiency　is　greater　than　91%.　Finally,　on　the　premise　of　meeting　the　interoperability　of　Q　and　DD　coils,　the　proposed　structure　also　has　a　certain　degree　of　antimisalignment　characteristics.　©　1982-2012　IEEE.
