摘　　要：基于电磁感应原理与等效电路法,建立超声波无接触电能传输系统的理论模型,推导出不同匹配形式下初、次边的等效阻抗及反射阻抗。应用Matlab软件对建立的反射阻抗模型进行求解分析,获得了次边匹配网络的工作频率和负载电阻对反射阻抗的影响;应用Magnet软件对建立的无接触电能传输系统进行仿真分析,获得了气隙、磁芯轴线偏移和磁芯轴线倾斜对电能传输效率和耦合系数的影响规律。对制造出的无接触电能传输系统进行传输效率测试,结果表明,电能传输效率达70.1%。Based on the principle of electromagnetic induction and equivalent circuit method,the theoretical model of ultrasonic non-contact power transmission system is established,and the equivalent impedance and the reflected impedance of the primary and secondary edges are obtained.Then the magnet software is used to simulate the non-contact power transmission system,and the influence of the air gap,the core axis offset and the core axis tilt on the transmission efficiency and the coupling coefficient is obtained.Finally,the transmission efficiency of the non-contact power transmission system is tested.The results show that the power transmission efficiency is 70.1%.
