摘　　要：针对无线能量传输系统中耦合器一、二次侧分离所造成的系统传输效率低、损耗大等问题,提出一种基于双口网络分析的补偿网络研究方法。建立适用于不同补偿网络类型分析的统一数学模型,设计了一种基于模型参数计算系统输出功率与传输效率的方法,用以衡量各种补偿网络结构的电路工作性能;基于Simulink平台构建仿真实验电路,通过改变负载电阻值检验各种补偿网络的电路工作稳定性;基于ANSYS有限元仿真软件,对耦合器周围电磁场分布进行仿真分析;综合理论分析与仿真实验结果,得到一次侧串联-二次侧并联补偿网络结构的电路工作性能最优,进而搭建带有该补偿网络的实物电路。实物实验结果表明:应用补偿网络后电路的输出功率与传输效率有明显提高。This paper presents a compensation network research method based on the double port network analysis. Firstly,we focus on the problems of low transmission efficiency and significant losses in the wireless power transmission system caused by big air gap between couplers. Then we present the uniform mathematical model which is applicable to different types of compensating network analyses, and suggest a method to calculate the output power and the transmission efficiency based on model parameters to measure the working performance of different compensation networks. Based on Simulink platform,the simulation circuit is built. By changing the load resistance, the working stability of the circuit with various compensating network is tested. Through ANSYS finite element simulation software,the distribution of the electromagnetic field around the coupler has been obtained. By integrating the theoretical analysis and the simulation results, the primaryseries-secondary-parallel circuit is found to maintain the optimal performance. The experiment results show that the output power and the transmission efficiency of the compensation network circuit are improved notably.
