For　electric　vehicles　(EVs)　equipped　with　an　onboard　charger　(OBC)　and　a　wireless　power　transfer　(WPT)　system,　there　will　be　two　charging　systems　in　the　EVs,　which　increases　the　cost,　weight,　and　complexity.　Based　on　the　proposed　design　of　magnetic　couplers,　this　letter　proposes　a　novel　integration　method　for　OBC　and　WPT　systems　of　EV　charging.　The　isolation　transformer　of　the　OBC　system　can　be　regarded　as　two　strongly　coupled　coils.　The　secondary-side　coil,　namely　the　receiving　coil,　can　also　be　loosely　coupled　with　the　transmitting　coil　of　the　WPT　system.　Thus,　the　receiving　coil,　the　compensation,　and　the　rectifier　of　both　the　OBC　and　WPT　systems　can　be　shared.　In　this　way,　the　EV　charging　system　can　be　capable　of　conductive　charging　and　wireless　charging　while　still　having　the　advantages　of　cost　effectiveness　and　high　power　density.　An　experimental　prototype　is　implemented　to　validate　the　proposal.
