摘　　要：自2007年以来非接触供电技术得到了迅速发展,但以电动机为负载的非接触供电技术研究较少。电动机是强冲击、大范围功率变化的机电负载。因此,在用非接触方式为电动机供电时,供电电压易随电动机运行状态的变化而明显波动。针对这一问题,本文在发射端采用LC补偿、在接收端采用串联补偿的方式,以实现发射线圈恒流特性、接收端稳压特性。介绍了LC/S补偿参数的设计方法,搭建了仿真和实验平台。分别利用LC/S和SS两种补偿方式对电动机直接起动和软起动过程进行了对比实验,结果表明,电动机起动前后,SS补偿方式发射线圈电流相对减小了6.03%,输出电压相对减小了22.48%;而LC/S补偿方式发射线圈电流相对减小了3.85%,输出电压相对减小了12.9%。由此表明,LC/S补偿方式具有更好的稳压和抗冲击特性,适于电动机类负载的非接触供电。Contactless power transmission technology has been developing rapidly since 2007,but study on contactless power transmission with the motor load is rare. Motor is a mechanicalelectricalload with strong impose and large power ranging. Therefore, when supplying power for motorwith contactless power transmission, power supply voltage will obviously fluctuate with the change ofthe motor running state. To solve this problem, this paper adapt LC compensation at transmitterterminal and series compensation at receiver terminal to keep the current of transmitter coil constantand to the voltage of receiver terminal stable. The method of LC/S parameter designing is given in thispaper. Simulation and experiment platform have been set up. The processes of motor direct start andsoft start are studied under the condition of LC/S compensation and SS compensation as comparingexperiments. The result is that compared with the current before motor starting, the current of transmittercoil reduces by 6.03% and output voltage reduces by 22.48% with SS compensation; the current oftransmitter coil reduces by 3.85% and the output voltage reduces by 12.9% with LC/S compensation.The result shows that LC/S compensation has better stability and impose resistance. This property isadvantageous to widely application with the load like motor whose power is supplied contactlessly.
