"There are two main battery voltage levels (400 V and 800 V) for electric vehicles (EVs). Conventional wireless power transfer (WPT) systems utilize different connection circuits to accommodate these voltages, which may cause additional power losses. This paper proposes a new LCC-LCC WPT system to accommodate both 400 V and 800 V battery voltages without compromising performance. The generalized mathematical model of the proposed system is presented.The current-sharing and voltage-sharing characteristics of the parallel and series connected circuits are analyzed. In addition, design considerations including power loss, power transfer capacity, and efficiency are discussed. Finally, an experimental prototype is built to verify the proposed system.The prototype can achieve 94.3% efficiency at a power level of 5 kW under 400 V and 800 V output voltages, which proves the effectiveness of the proposed method."
