In　wireless　charging　applications,　multiple　phases　of　the　inverter　can　be　paralleled　to　enhance　the　power　level.　Even　though　the　same　pulse-width　modulated　signals　are　applied　for　the　corresponding　switches,　there　can　still　be　phase　differences　in　the　driving　pulses　which　directly　turn　on/off　the　switches,　due　to　the　inconsistency　in　the　switch　parameters　or　driving　circuits.　The　different　driving　pulses　can　result　in　large　circulating　currents,　which　decrease　the　power　level.　Current　balancing　techniques　can　be　adopted　to　solve　this　issue.　This　paper　proposes　a　passive　current　balancing　method　for　wireless　charging.　Compared　with　the　existing　method,　the　proposed　method　can　reduce　the　number　of　coupled　inductors　by　half　and　balance　every　two　sources　to　achieve　good　current　balancing　performance.　Experimental　results　have　validated　the　effectiveness　of　the　proposed　method.　©　2021　IEEE.
