In　recent　years,　electric　vehicles　have　developed　rapidly,　but　the　traditional　wired　charging　method　cannot　meet　the　requirements　of　automation　and　convenience　of　the　vehicles.　Therefore,　the　wireless　charging　technology　for　electric　vehicles　has　been　widely　studied　for　its　safety　and　convenience.　The　common　coil　structures　in　the　wireless　charging　system　include　the　unipolar　coil,　the　bipolar　coil　and　the　quadrupole　coil.　Due　to　the　adaptation　problems　of　different　manufacturers,　a　new　type　of　coil　should　be　designed　to　get　compatible　with　these　coils　to　achieve　the　interoperability.　This　paper　presents　a　new　decoupled　quadruple　monopole　receiving　coil　structure,　which　may　achieve　the　interoperability　with　different　transmitting　coils.　The　decoupling　between　the　four　receiving　coils　is　realized　by　adding　a　decoupling　winding　inside　the　receiving　coils.　Then,　the　total　mutual　inductance　between　the　transmitting　coil　and　the　four　monopole　receiving　coils　is　the　sum　of　the　absolute　value　of　the　mutual　inductance　between　the　transmitting　coil　and　the　four　monopole　coils　by　the　series　diode　rectifier.　A　set　of　experimental　prototype　is　built　to　verify　the　effectiveness　of　the　scheme.　The　proposed　four-monopole　receiving　coil　is　able　to　be　compatible　with　the　unipolar　coil,　the　bipolar　coil　and　the　quadrupole　coil,　realizing　the　interoperability　with　different　receiving　coils.　©　2024　Power　System　Technology　Press.　All　rights　reserved.
