摘要/Abstract

摘要：

基于 SN ( 串联-无补偿) 的无线输电系统具有接收侧结构简单、在强耦合和高品质因数的情况下效率较高的优点。为了解决因发射线圈和接收线圈之间的互感发生偏移及负载变化引起的输出电压不恒定的问题，文中提出了一种原边检测控制方式，通过测量发射线圈侧的输入电压、电流及二者之间的相角差来计算实际的互感和接收线圈侧的输出电压，并在此基础上实现闭环控制。文中首先分析了基于 SN 补偿拓扑的系统的原边检测原理以及系统的效率特性，然后采用 Simulink 仿真软件分别进行开环和闭环的仿真来验证理论分析的正确性，最后通过实验验证该控制方法的可行性。仿真与实验分析表明，文中提出的控制方式是正确、有效的。

Abstract:

The wireless power transfer system based on SN ( Series-None compensation) has the advantages of high efficiency in the case of strong coupling and high quality factor as well as simple-structured receiver． In order to deal with the unstable voltage caused by mutual inductance shifting and load fluctuation，a primary side detection method was proposed． The actual mutual inductance and output voltage of the receiving side were calculated by measuring the input voltage and current of the transmitting side and the phase difference between them． The closedloop control was realized on this basis． In this paper，the principle of the primary side detection of the system based on Series-None compensation topology and the efficiency characteristics of the system were analyzed firstly． Then the theoretical analysis was verified by the simulations of open loop and closed loop respectively with Simulink simulation software． Finally，the feasibility of the control method was verified by experiments． Simulation and experimental analysis proves that the control method proposed in the article is correct and effective．

Key words: wireless power transfer, compensation topology, primary side control
