The　compensation　network　in　the　wireless　power　transfer　(WPT)　system　directly　affects　the　performance　of　the　system　and　is　one　of　the　research　focuses　in　the　WPT　technology.　Considering　that　the　transmitter　side　and　the　receiver　side　are　challenging　to　resonate　simultaneously　in　the　existing　compensation　network,　the　compensation　capacitance　of　the　transmitter　side　cannot　be　used　in　some　special　applications.　Based　on　the　multi-solvability　of　the　transformer　T-network　model,　this　paper　deduces　the　principle　of　unilateral　compensation　to　achieve　constant　voltage　or　constant　current　output.　It　proposes　a　series-parallel　(/SP)　compensation　network　structure　that　can　realize　any　stable　current　output　characteristics.　The　structure　obtains　different　transfer　admittance　characteristics　by　compensating　and　controlling　the　leakage　inductance　impedance　on　the　receiver　side.　The　experimental　results　verify　the　correctness　and　feasibility　of　the　theoretical　analysis.　©　2022　IEEE.
