In　some　applications　of　wireless　power　transfer,　the　magnetic　coupling　between　the　transmitter　and　the　receiver　can　be　enhanced　to　increase　the　transmission　efficiency.　And　due　to　the　strong　coupling,　the　receiver　compensation　can　be　eliminated,　resulting　in　a　compact　receiver　size.　In　this　way,　a　series-none　(S　N)　topology　is　formed.　In　this　paper,　a　parameter　identification　method　for　the　S-N　topology　is　proposed.　The　identifications　of　the　mutual　inductance　and　the　load　resistance　are　realized　by　the　inverter　output　voltage,　current,　and　the　input　impedance　angle.　To　validate　the　parameter　estimation　accuracy,　an　S-N　topology　WPT　prototype　was　conducted.　The　experimental　results　show　that　the　maximum　errors　of　the　mutual　inductance　and　load　identification　are　0.4%　and　2.23%,　respectively,　under　the　system　resonance　condition.　©　2025　IEEE.
