For　a　wireless　power　transfer　(WPT)　system,　the　misalignment　of　coils　can　easily　cause　low　transfer　efficiency,　unstable　output　current　and　over-current　of　transmitting　coil.　Therefore,　this　paper　proposes　a　constant　current　output　WPT　system　and　its　parameter　design　method　with　high　anti-offset　performance.　In　the　proposed　system,　the　LCC-LCC　and　S-S　compensation　network　are　connected　in　input　series　and　output　series,　and　the　magnetic　coupling　structure　of　quadruple-D　quadrature　pads　is　adopted.　Then,　through　reasonable　parameter　configuration,　not　only　the　load　independent　constant　current　output　can　be　realized,　but　also　anti-x　direction,　y-direction,　z-direction　and　anti-xy　direction　can　be　realized.　Moreover,　the　over-current　of　the　transmitting　coil　is　avoided.　By　analyzing　the　transfer　property　of　the　proposed　system,　it　is　proved　theoretically　that　the　system　has　good　anti-offset　performance.　Finally,　an　experimental　platform　with　280W　is　built　to　verify　the　correctness　and　feasibility　of　the　theoretical　analysis.　©　2022,　Electrical　Technology　Press　Co.　Ltd.　All　right　reserved.
