摘要
对磁耦合谐振式无线电能传输系统模型进行分析,采用电路理论得出系统传输效率的表达式。通过MATLAB仿真得出系统传输效率随系统频率、负载、传输距离和谐振线圈参数变化的规律,得出磁耦合谐振式无线电能传输系统对系统频率、负载、传输距离、线圈半径、线圈匝数有最优值的结论,为提高无线电能传输效率提供了参考和借鉴。
This paper analyzes the magnetic coupled resonant wireless power transmission system model, obtaining the expression of the system transmission efficiency expression from the circuit theory. The MATLAB simulation results show that the system changes of transmission efficiency of system frequency, load, distance and coil parameters. The magnetic coupled resonant wireless power transmission system has the best frequency, and the optimal load, the optimal transmission distance, optimal coil radius and optimal coil turns. This provides reference for the further design to improve the power and efficiency in wireless power transmission system.
