A　novel　passive　current　sharing　method　for　a　multiphase　wireless　power　transfer　(WPT)　system　is　proposed　in　this　letter.　For　an　N-phase　inverter,　there　would　be　N　compensating　inductors　in　the　inductor-capacitor-capacitor　series　(LCC-S)　compensated　WPT　system.　The　proposed　scheme　introduces　N　external　parallel　resonant　branches　coupled　with　these　N　compensating　inductors.　In　this　way,　an　extremely　large　impedance　is　introduced　in　each　loop　of　the　circulating　currents　so　as　to　balance　the　phase　currents.　No　additional　passive　components　with　the　rated　power　level　are　added　to　the　power　transfer　channel.　The　proposed　method　employs　two　coupled　inductors,　which　is　easy　to　realize.　Two　new　integrated　structures　for　coupled　inductors　are　introduced.　The　mathematical　model　and　the　current　sharing　principle　of　the　proposed　method　are　analyzed　in　detail.　A　1.6-kW　LCC-S　compensated　WPT　experimental　prototype　with　a　four-phase　inverter　and　the　experimental　results　verify　the　effectiveness　of　the　proposed　current　sharing　method.　©　1986-2012　IEEE.
