In　this　paper　a　new　idea　is　proposed　according　to　which　variable　constant　output　current　can　be　got　by　compensation　network　parameters　design　for　a　given　magnetic　coupling　system　based　on　the　multi-solutions　of　the　transformer　T　model　and　the　leakage　inductance　compensation　theory.　And　the　principle　and　the　parameters　calculation　method　of　compensation　network　with　different　variable　transfer　admittance　were　analyzed　based　on　electrical　circuit　theory.　Also,　the　parameters　design　method　with　the　consideration　of　the　winding　resistance　and　its　frequency　shifts　characteristics　were　modeled　and　analyzed.　The　results　show　when　the　equivalent　ratio　n　decreases　the　sensitive　of　the　parameters　decreases　too,　which　can　improve　the　load　adjustment　of　the　wireless　power　transfer　(WPT).　Finally,　the　prototype　was　constructed　and　the　experiment　results　verified　the　theory　analysis　to　be　correct.　©　2017,　The　editorial　office　of　Transaction　of　China　Electrotechnical　Society.　All　right　reserved.
