摘要

本文对电容式无线电力传输(CWPT)系统中的LCCL和CLLC谐振补偿进行了比较。对几种补偿拓扑进行了综述。从这一分析中可以看出，这两种拓扑结构代表了更有希望的高功率应用补偿，例如电动汽车(EV)无线充电。分析了各拓扑的频率特性，研究了等效输入阻抗和电压传递函数。通过LTspice仿真，评估了各补偿器件在负载、耦合寄生电阻变化情况下的输出功率和效率。

Frequency Analysis and Comparison of LCCL and CLLC Compensations for Capacitive Wireless Power Transfer

In this paper a comparison between a LCCL and CLLC resonant compensations for Capacitive Wireless Power Transfer (CWPT) system is presented. A review of several compensation topologies is presented. From this analysis emerges that these two topologies represent the more promising compensation for high power applications, such as Electric Vehicle (EV) wireless charging. The frequency behavior of each topology is analyzed studying the equivalent input impedance and the voltage transfer function. After design of each compensation to operate at optimum operating condition, the output power and the efficiency are evaluated under load, coupling parasitic resistances variations through LTspice simulations.
