Many　low-power　gadgets　can　employ　wireless　charging　technology,　but　this　causes　significant　changes　in　mutual　inductance　while　the　device　is　in　motion　during　charging.　This　paper　offers　a　design　approach　that　makes　use　of　reverse　windings　(RWs)　in　order　to　solve　this　issue　by　maximizing　average　mutual　inductance　and　stabilizing　its　variance.　The　RW　extends　from　the　planer　coil　to　the　solenoid.　Through　the　optimization　process,　the　degree　of　mutual　inductance　fluctuation　is　reduced　nearly　twice.　The　transmitter　side　places　seven　solenoids　in　a　hexagonal　package,　and　the　receiver　can　cover　a　larger　transmission　area　during　migration.　The　effectiveness　of　the　suggested　design　method　has　been　validated　by　the　experimental　results.　©　2023　IEEE.
