Abstract

This paper presents a research on the characteristics of wireless power transfer (WPT) system based on LCC/N magnetic integration compensation circuit. Compared with the traditional compensation circuits, the LCC/N compensation circuit has no compensation circuit on the secondary side and integrates the compensation inductor on the primary side into the transmitter. First, the two-port network considering the coupling relationship between magnetic integration compensation inductance and receiver coil is established. Then, based on the two-port network, the output impedance angle of the inverter, transmission power and efficiency of the WPT system employing LCC/N compensation circuit is analyzed under variations of coupling coefficient and load. Finally, the analysis of the characteristics of the WPT system based on the LCC/N magnetic integration compensation circuit is verified by simulations and experiments. And the results show that the analysis of characteristics is effective.

基于LCC/N磁积分补偿电路的无线输电系统特性研究

本文研究了基于LCC/N磁积分补偿电路的无线电力传输(WPT)系统特性。与传统的补偿电路相比，LCC/N补偿电路没有二次侧补偿电路，将一次侧的补偿电感集成到发射机中。首先，建立了考虑磁积分补偿电感与接收线圈耦合关系的双端口网络;然后，基于双端口网络，分析了在耦合系数和负载变化下，采用LCC/N补偿电路的WPT系统的逆变器输出阻抗角、传输功率和效率。最后，通过仿真和实验验证了基于LCC/N磁积分补偿电路的WPT系统的特性分析。结果表明，特性分析是有效的。
