The　traditional　arrangement　to　charge　multiple　electric　vehicles　(EVs)　in　an　EV　wireless　charging　station　is　to　share　a　common　dc　bus　for　multiple　inverters.　To　charge　EVs　with　different　power　levels,　the　charging　modules　should　be　designed　to　be　different,　which　will　increase　the　cost　and　complexity.　A　modular　design　approach　for　a　wireless　charging　station　with　a　common　ac　bus　is　proposed　in　this　article.　All　the　charging　modules　are　paralleled　on　the　ac　side　of　the　inverters　through　transformers,　and　each　charging　module　can　be　designed　to　be　the　same　and　fully　utilized　through　the　proposed　arrangement.　A　voltage　regulation　strategy　based　on　the　active　rectifier　is　proposed.　The　output　voltage　and　power　can　be　adjusted　through　the　control　strategy.　An　experimental　prototype　with　two　modules　and　three　charging　ports　is　built　and　the　operations　with　different　output　ports　are　carried　out.　The　proposed　system　can　charge　multiple　EVs,　and　the　charging　voltage　of　each　port　can　be　adjusted　independently　through　the　proposed　control　strategy.　©　2013　IEEE.
