In　recent　years,　the　rapid　development　of　electric　vehicles　(EVs)　has　led　to　the　continuous　innovation　of　the　charging　technology.　EV　wireless　charging　is　safer　and　more　convenient　than　conductive　charging,　and　the　researches　about　this　aspect　are　more　in-depth.　Three　types　of　planar　coils,　namely　unipolar　coil　(Q),　bipolar　coil　(DD),　and　quadrupolar　coils　(QUA)　are　usually　utilized　at　the　receiving　side　(Rx)　in　the　EV.　According　to　different　design　requirements,　various　types　of　Rx　coils　will　be　installed　by　the　manufacturers　of　EVs.　Modifying　the　structure　of　the　transmitting　coils　(Tx)　to　improve　interoperability　is　the　key　issue　of　the　wireless　charging　technology.　In　this　paper,　a　multi-channel　topology　with　four　decoupled　Q　Tx　coils　is　proposed.　The　vector　synthesis　strategy　of　equivalent　transmitting　mutual　inductance　is　adopted.　Based　on　the　achievement　of　interoperability　for　three　types　of　Tx　coils,　the　high　misalignment　tolerance　on　the　directions　of　both　X/Y　axes　is　also　achieved.　An　experimental　prototype　is　built,　and　the　effectiveness　of　the　topology　is　verified.　The　proposed　multi-channel　topology　is　compatible　with　Q,　DD　and　QUA　coils,　and　high　misalignment　tolerance　is　achieved.　©　2015　IEEE.
