In　an　electric　vehicle　wireless　charging　system,　the　dramatic　variation　of　the　mutual　inductance　caused　by　the　coil　misalignment　is　an　urgent　problem　to　be　solved.　An　offset-resistant　wireless　charging　system　based　on　dual　decoupled　receiving　coils　is　proposed,　with　one　receiving　coil　as　the　unipolar　coil　and　the　other　as　the　quadrupolar　coil.　With　series　compensation,　they　are　connected　in　series　through　the　diode　rectifier.　In　this　way,　the　total　equivalent　mutual　inductance　is　the　summation　of　the　absolute　values　of　the　two　mutual　inductances.　Thus,　the　total　equivalent　mutual　inductance　can　remain　stable　against　misalignment,　guaranteeing　a　stable　system　output.　Experimental　results　confirm　that　the　designed　system　has　good　misalignment　tolerance　capability　in　two　perpendicular　directions,　enabling　stable　and　efficient　power　transmission.　Along　the　misalignment,　the　output　voltage　fluctuation　is　only　2.81%　with　the　highest　system　efficiency　of　94.68%.　©　1982-2012　IEEE.
