A Cost-Effective Wireless Power System with CC/CV Output Based on Reconfigurable Topology

Wireless power transfer (WPT) is widely exerted in the application with battery charging. Considering the safety and effectiveness, WPT system with the constant current (CC) output and constant voltage (CV) output is demanded to provide power for battery. In this paper, a cost-effective reconfigurable circuit based on CLC-S topology is proposed. With the reform of the proposed reconfigurable circuit, there is no need for extra passive component, and only one ac switch module is added. With the assistance of the extra ac switch module, the CC and CV output can be implemented in the proposed reconfigurable circuit. Finally, an experimental setup is established. The results show that the system can obtain the current output current with 2% fluctuation and the current output voltage with 5% fluctuation in CC or CV mode with the 1000% variation of the load, respectively.
