Compact Anti-offset WPT System With Dual-coupled SP-S Compensation

Translated Abstract

Pad　misalignment　is　almost　inevitable　in　most　wireless　power　transfer(WPT)systems,which　leads　to　system　performance　degradation　due　to　the　variation　of　system　parameters.Based　on　S-S　and　P-S　compensation　topology,this　paper　proposes　a　compact　WPT　system　with　dual-coupled　SP-S　compensation　with　anti-offset　characteristics.Two　coaxially　arranged,mutually　decoupled,rounded　square　coils　are　used　as　the　energy　transmitting　coils,which　are　coupled　with　a　single　square　receiving　coil　to　improve　the　anti-offset　tolerance　in　the　X　and　Y　directions.In　the　process　of　receiving　coil　offset,the　output　of　one　transmitting　coil　loop　is　increased　and　the　output　of　the　other　coil　loop　is　reduced　by　resonance　parameter　configuration,so　that　the　system　output　fluctuates　gently　with　the　offset　of　the　receiving　coil.The　design　method　of　the　structural　parameters　of　the　square　decoupling　coil　is　put　forward　and　the　influence　of　shunt　compensation　capacitance　on　the　offset　resistance　of　output　is　also　analyzed.An　experimental　platform　is　built　to　verify　the　feasibility　of　the　proposed　method　and　the　anti-misalignment　performance　of　the　proposed　WPT　system.
