摘要
针对传统接触式供电模式的不足,设计了一种小功率磁耦合谐振式无线供电系统,以此研究该系统的传输特性。主要利用电路耦合理论,建立系统的等效电路模型,并借助MATLAB仿真分析系统参数对传输特性的影响,包括谐振频率、负载阻值和耦合系数,最终搭建了小功率无线供电系统试验平台,对系统的传输特性进行了试验验证。传输特性试验结果与MATLAB仿真分析结果具有较高的吻合度,表明设计的小功率磁耦合谐振式无线供电系统能够进行良好的无线能量传输,同时也为小功率无线充电设备的发展提供新思路。
Aiming at the shortcomings of the traditional contact power supply mode,a low-power magnetic coupling resonant wireless power supply system was designed to study the transmission characteristics of the system.The circuit coupling theory is mainly used to establish the equivalent circuit model of the system.The influence of system parameters on the transmission characteristics,including the resonant frequency,load resistance and coupling coefficient,is simulated by MATLAB.Finally,a low-power wireless power supply system test platform is built.The transmission characteristics of the system were tested and verified.The transmission characteristic test results are in good agreement with the MATLAB simulation analysis results,indicating that the designed low-power magnetic coupling resonant wireless power supply system can perform good wireless energy transmission,and also provide new ideas for the development of low-power wireless charging equipment.
