This　paper　proposes　a　modular　single-channel　dual-frequency　wireless　power　transfer　system　for　industrial　power　supply　with　a　dual-frequency　hybrid　compensation　topology.　The　series-series　topology　is　adopted　with　working　frequency　locating　at　its　two　constant-voltage　(CV)　output　points　for　the　CV　outputs.　The　band-stop　filter　with　a　parallel　resonant　network　is　designed　to　filter　the　undesired　frequency　component　and　the　series　series-parallel　resonant　network　is　formed　to　avoid　the　impact　of　the　band-stop　filter　on　the　CV　output.　In　this　way,　selective　power　transfer　with　CV　outputs　can　be　achieved.　The　mathematical　model　of　the　proposed　compensation　topology　has　been　established　and　analyzed.　The　transmission　coils　and　the　compensating　inductors　are　integrated　to　achieve　a　compact　structure.　An　experimental　prototype　is　built　to　verify　the　theoretical　analysis.　The　system　realizes　CV　outputs　and　supplies　power　to　different　loads　at　different　operating　frequencies,　with　transfer　efficiency　of　more　than　83.94%　and　output　power　of　99.53　W.　　©　2023　IEEE.
