摘要

本文提出了一种仅处理发送端信息的距离检测系统。通过使用距离检测系统，数字TX线圈的半径可以根据距离自动变化，从而达到最大的跟踪效率。制作了无线电力传输(WPT)样机，实验结果表明，与使用半径恒定的传统TX线圈相比，在距离为RX线圈半径的4倍时，效率从12%提高到20%。

Distance Detection System for Digital Transmitter Coil Achieving Distance-Variation-Tolerant Wireless Power Transfer

In this paper, a distance detection system that only processes the information in the transmitter (TX) side is proposed. By using the distance detection system, the radius of the digital TX coil can change automatically depending on the distance and thus achieve the maximum efficiency tracking. A wireless power transfer (WPT) prototype is fabricated and experimental results demonstrate that, compared with using the conventional TX coil with a constant radius, the efficiency is improved from 12% to 20% at the distance of 4 times the RX coil radius.
