Wireless　power　transfer　(WPT)　has　been　used　in　various　fields,　such　as　electric　vehicles　(EVs).　Misalignment　tolerance　is　an　important　characteristic　to　evaluate　the　WPT　system　performance,　especially　in　the　EV　wireless　charging　system.　This　paper　proposes　a　decoupling　method　for　multiple　receiving　coils　and　the　series　connected　diode　rectifiers　to　achieve　misalignment　tolerance.　Three　receiving　coils　are　designed　to　be　decoupled　from　each　other　and　the　sum　of　the　absolute　values　of　their　mutual　inductances　with　the　transmitting　coil　are　smoothed　to　improve　the　anti-offset　performance.　The　mathematical　model　is　built　and　analyzed.　The　expressions　of　the　output　current,　output　voltage,　output　power,　and　transfer　efficiency　have　been　derived.　The　experimental　results　reveal　that　the　proposed　WPT　system　can　achieve　misalignment　tolerance　with　high　efficiency.　　©　2023　IEEE.
