Abstract

Wireless charging of electric vehicle (EV) is achieved by an inductive power transfer (IPT) technique in a midrange power transfer application. In this paper, a modified class E converter topology is proposed for an efficient power transfer application at lower switching frequency compared to the class E wireless power transfer (WPT) system. The converter uses minimum semiconductor switches to perform the inverter action, thereby reducing the cost and making the IPT system more compact. The converter shows high efficiency at lower coupling coefficient for heavy load application. The simulation and experimental results substantiate the notion about the theoretical aspect.
