Abstract

This paper proposes a novel control strategy for wireless power transfer (WPT) circuits that achieves both load voltage regulation and maximum efficiency control for varied resistive loads. The proposed method is based on the characteristic that the input impedance of a switching voltage regulator depends on its input voltage. The switching regulator is utilized not only for load voltage regulation but also for impedance conversion to maximize the transfer efficiency. External communication circuits for feedback control from the secondary side to the primary side are unnecessary as the controllers on both sides operate independently. Experimental results approximately match the derived theoretical values and validate the proposed method.

一种利用开关稳压器的无线电力传输电路中负载电压调节和功率传输效率最大化的新方法

本文提出了一种新的无线电力传输电路控制策略，既能实现负载电压调节，又能实现对各种电阻性负载的最大效率控制。该方法基于开关稳压器的输入阻抗取决于其输入电压的特性。开关稳压器不仅用于负载电压调节，而且用于阻抗转换，以最大限度地提高传输效率。从二次侧到一次侧的反馈控制不需要外部通信电路，因为两边的控制器都是独立工作的。实验结果与理论值基本吻合，验证了该方法的有效性。
