摘要

匹配网络对于电容式无线电力传输(CWPT)系统非常重要，因为它们提供了必要的电压增益和阻抗补偿。耦合电容间的电压对传输功率和效率有很大影响。介绍了CWPT系统双面LC匹配网络的设计方法。讨论了一次侧电压与二次侧电压的比值，以实现所需的传输功率并优化匹配网络的效率。通过对匹配网络的阻抗分析，满足了逆变级零电压开关的要求。基于数学模型制定了设计流程，并在6.78MHz的1kW CWPT系统中进行了仿真验证。

Design of Efficient Double-Sided LC Matching Networks for Capacitive Wireless Power Transfer System

Matching networks are important for capacitive wireless power transfer (CWPT) systems as they provide necessary voltage gain and impedance compensation. The voltages across coupling capacitors greatly affect the transmitted power and efficiency. This paper introduces a method to design double-sided LC matching networks for the CWPT system. The ratio of the voltage across the primary side to the voltage across the secondary side is discussed to realize the required transmitted power and optimize the efficiency of the matching networks. The requirement of zero-voltage switching (ZVS) of the inverter stage is satisfied based on the impedance analysis of the matching networks. The design process is developed based on the mathematical model and verified in simulation for a 1kW CWPT system at 6.78MHz.
