Wireless　charging　of　automated　guided　vehicles　(AGVs)　has　been　widely　used　because　of　its　high　security　and　convenience.　However,　due　to　the　inevitable　misalignment　between　the　coupling　coils,　the　charging　system　cannot　maintain　the　constant　current　(CC)　or　constant　voltage　(CV)　output.　Therefore,　this　article　proposes　a　misalignment-tolerant　fractional-order　wireless　power　transfer　(FOWPT)　system　with　CC　or　CV　output.　According　to　the　principle　of　the　fractional-order　autonomous　circuit,　the　natural　resonant　frequency　and　operating　frequency　can　be　adjusted　adaptively　with　the　change　of　transfer　distance　and　load.　Benefiting　from　the　frequency　characteristics　and　the　new　implementation　method　of　the　FOWPT,　the　system　maintains　CC　and　CV　output,　and　the　horizontal　and　vertical　misalignment　tolerances　are　within　44.4%　and　22.2%,　respectively.　Therefore,　the　proposed　system　improves　the　freedom　and　convenience　of　charging,　and　provides　a　new　wireless　charging　solution　for　AGVs.　Future　article　will　focus　on　more　concise　modeling　and　implementation　methods　of　fractional-order　systems,　and　improving　the　performance　of　the　FOWPT.　©　1986-2012　IEEE.
