As the increasing demands for the constant voltage (CV) charging of multiple loads, this article proposes an LC compensated wireless power transfer (WPT) system with multiple CV outputs function. The proposed WPT system can achieve multiple voltage outputs without decoupling method. Each voltage output channel is composed of a compensation capacitor and a compensation inductor connected in series. By configuring different compensation inductors and capacitors for each output channel, it can achieve different CV outputs without affecting the output voltage of other output channels. In addition, the system can achieve near-zero phase angle (ZPA) and zero-voltage switching (ZVS) operations, which can improve system efficiency. Finally, the correctness and rationality of the proposed WPT system is verified by built an experimental prototype with two CV output channels.
