摘　　要：为了解决传统电磁感应式无线输电的低效率问题,设计了谐振耦合式无线输电系统,并通过理论计算、电路设计与仿真,分析了谐振耦合式的无线电能传输的效率影响因素以及线圈强耦合下所产生的频率分裂现象。在理论分析的基础上,制作了无线电能传输装置,包括直流电源、高频逆变电路、发射接收线圈、整流电路。实验结果表明,当接收端采用串联谐振时,负载越小,效率越高;当接收端采用并联谐振时,负载越大,效率越高。In order to solve the low efficiency of conventional inductively coupled power transfer,the coupled resonances wireless power transfer system is designed.The influence factor of efficiency and the frequency division of the highly couple coil are anal-ysed by theoretical calculation,circuit design and simulation.The device of wireless power transfer is design,and it includes di-rect-current source,high frequency inverter circuit and coupled coil and rectifier circuit.The result indicates ：when the receiving circuit adopts the series resonance,the efficiency is higher with a lower resistance of load.When the receiving circuit adopts the parallel resonance,the efficiency is higher with a higher resistance of load.
