摘要

本文介绍了一种新的基于单对电场耦合的无回流路径无线电力传输系统。这种单触点电容功率传输(CPT)系统有助于提高耦合板之间的耦合容差。E类变换器驱动LCLC谐振电路对耦合板初级侧电压进行升压，CLCL谐振电路对负载输出电流进行升压。建立了一个实用的原型，并证明了3.8 W的功率可以通过一对铜耦合板(100mm ×100mm)在完全对准。结果表明，单线CPT系统对耦合板间的侧向和角向偏差都有较大的耦合容差。

A single-wire capacitive power transfer system with large coupling alignment tolerance

This paper introduces a new Wireless Power Transfer (WPT) system based on single pair of electric field coupling without a current return path. Such a single-contact Capacitive Power Transfer (CPT) system helps to enhance the coupling tolerance between the coupled plates. A class E converter is designed to drive an LCLC resonant circuit to boost the voltage at the primary side of the coupling plate, while a CLCL resonant circuit is used to boost the output current to the load. A practical prototype is built, and it has demonstrated that 3.8 W of power can be transferred across a single pair of copper coupling plates (100mm ×100mm) at full alignment. And it has found that the single-wire CPT system has a large coupling tolerance against both lateral and angular misalignments between the coupled plates.
