Abstract
Wireless power transfer (WPT) systems is widely applied for the battery charging. Considering the safety and effectiveness, WPT system with the constant current (CC) and constant voltage (CV) output is required to provide power for battery. A cost-effective reconfigurable topology is proposed to obtain CC output and CV output by adjusting the status of the inverter and auxiliary switches in circuit is proposed. With the reform of the proposed method, fewer passive components can be employed to achieve the CC/CV charging of the battery in charging process. The proposed method has been verified with an experimental prototype and results show that the fluctuation of the charging current is less than 2% in CC mode, and that of charging voltage in CV mode is within 5% during the whole charging process.
