At present, wireless power transfer (WPT) technique has beensuccessfully adoptedin many applicationsnot only forthe low power applicationsas in medical device and consumer electronics but also in the electric vehicle (EV) high power application[1-3].Especially in the wireless EV’s battery charger, the use of magnetically coupling provided no directly physical and electrical contact between the electric source and load which make them more safety and more convenient than the conventional conductive EV’s battery charger[4].To compensate for the reactive power required from the coupled coilsneededtotransfer power at large air gap, primary and/or secondary windingalways compensate in series or parallel with the capacitor whichformedthe four basic compensation topologiesas series-series (SS), series-parallel (SP), parallel-series (PS), and parallel-parallel (PP)topology[5].Since, in SS topology as shown in Fig. 1(a), the power transfer capability may decrease if a small load is connectedor when operating at high primary ZPA frequency due to the increase of the reflected resistance in the primary side. Moreover, it may also resultin the primary current’s distortion due to the
