Abstract：

Wireless　charging　for　automatic　guided　vehicles　(AGVs)　has　gained　increasing　interest.　One　of　the　charging　issue　is　misalignment　tolerance.　This　brief　proposes　an　AGV　static　wireless　charging　system　with　dual　receiving　coils　to　achieve　the　anti-offset　characteristic.　The　two　receiving　coils　are　specially　designed　to　be　decoupled　and　have　a　smooth　coupling　coefficient　variation　along　misalignment.　They　are　connected　to　two　diode　rectifiers,　which　are　paralleled　on　the　DC　side.　The　proposed　WPT　system　will　automatically　choose　the　maximum　coupling　for　power　transfer.　In　this　way,　the　misalignment-tolerant　WPT　system　can　be　achieved.　An　experimental　prototype　is　implemented　to　validate　the　proposal.
