In　some　industrial　application　scenarios,　multiple　constant-voltage　(CV)　outputs　with　galvanic　isolation　are　required.　Selective　power　transfer　among　the　CV　outputs　can　enable　its　flexibility.　This　article　proposes　a　modular　single-channel　wireless　power　transfer　system　for　industrial　power　supply　with　a　dual-frequency　hybrid　compensation　topology.　The　series-series　topology　is　adopted　for　CV　outputs　at　the　two　CV　output　frequency　points.　The　bandstop　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　bandstop　filter　on　the　desired　frequency　component.　In　this　way,　selective　power　transfer　with　CV　outputs　can　be　achieved　by　changing　the　working　frequency.　The　mathematical　model　of　the　proposed　compensation　topology　is　established　and　analyzed.　The　transmission　coils　and　the　compensating　inductors　are　integrated　to　achieve　a　compact　structure.　The　design　principles　of　the　coupler　parameters　are　proposed,　and　a　design　example　is　given.　An　experimental　prototype　is　built　to　verify　the　theoretical　analysis.　The　system　realizes　CV　outputs　and　supplies　power　to　different　loads　at　different　working　frequencies,　with　an　average　transfer　efficiency　of　85.23%　and　a　maximum　output　power　of　85.95　W.
