摘要
针对磁耦合谐振式无线输电系统在实际应用中发射线圈与接收线圈难以对称、系统传输效率较低的问题,搭建了发射线圈大、接收线圈小的不对称系统模型,提出在发射线圈和接收线圈间增加中继线圈的方法来提高系统传输效率,并提出一种中继线圈与发射线圈同轴同平面的结构;通过仿真对比了该方法与增加发射线圈匝数方法对系统传输效率的影响,结果表明增加中继线圈的方法能更有效地提高系统传输效率,且体积更小;在实验室环境下搭建了系统实验平台,验证了理论分析和仿真结论的正确性。
For asymmetric transmitting coil and receiving coil of magnetic coupling resonant wireless power transmission system in practical application and low system transmission efficiency,an asymmetric system model was built whose transmitting coil was larger than receiving coil.A method for improving system transmission efficiency was proposed which was by increasing repeating coil between the transmitting coil and the receiving coil.A structure was proposed,namely the repeating coil and the transmitting coil were coaxial and in the same plane.The simulation was done to compare the method with a method of increasing turn number of the transmitter coil about influence on system transmission efficiency.The simulation results show that the former can improve the transmission efficiency more efficiently with a smaller volume.Experimental platform of the system was built in laboratory to verify correctness of theoretical analysis and simulation.
