This paper presents design process and working of wireless power transfer system. WPT system is designed to add convenience and sense of reliability to end consumer’s life. WPT system has been developed for small electric city car which has power requirement of 560 W. Lead acid battery having maximum terminal voltage of 56 V and maximum charging current is 10 A. Depending on components used to transfer power wirelessly, wireless power transfer (WPT) technology has been divided into three parts, i.e., capacitive WPT, inductive WPT and magnetic gear WPT. Among other methods, resonant inductive coupling method is advantageous. Resonant inductive WPT is used to charge the electric vehicle (EV). Inductive power transfer (IPT) mainly consists of the two coils separated by the air. One coil is placed on ground and other on base plate of electric vehicle. Along with the coil, power converters are also present in the circuitry. On the transmitting side, power supply circuitry is connected to transmitting coil placed on the ground, and on receiving side, power conditioning circuitry is placed on vehicle side.
