In　electric　vehicle　(EV)　dynamic　wireless　power　transfer　(DWPT)　systems,　changes　in　the　mutual　inductance　will　lead　to　fluctuations　in　the　output　voltage　and　efficiency.　In　this　article,　a　triple-coil　receiver　with　a　novel　triple-diode　rectifier　structure　that　can　reduce　the　number　of　diodes　is　proposed,　with　each　phase　connected　to　one　of　the　triple　decoupling　coils　(TDCs)　on　the　receiving　side.　Decoupling　is　achieved　with　partial　overlapping.　Reverse　windings　are　integrated　into　TDC　to　smooth　the　mutual　inductance　fluctuations.　The　proposed　novel　rectifier　switches　between　the　single-coil　receiving　mode　and　the　dual-coil　receiving　mode　in　response　to　the　different　positions　of　the　EV.　The　proposed　magnetic　coupler　structure　and　the　novel　triple-diode　rectifier　guarantee　a　constant　output　during　movement.　The　effectiveness　of　the　proposed　DWPT　system　has　been　verified　by　the　experimental　prototype.　The　output　voltage　remains　stable　over　a　long　range,　with　a　fluctuation　of　only　about　3.49%.　The　proposed　DWPT　system　cannot　only　reduce　the　number　of　track　coils　but　also　extend　the　novel　triple-diode　rectifier　to　multiple　coils　with　a　reduced　diode　number,　which　has　a　good　reference　value.
