摘要
磁耦合谐振式无线电能传输(MCR-WPT)为近几年较为热门的研究话题,在静态研究已经饱和的情况下,如何对旋转设备进行WPT成为了新一轮热点。目前,对旋转设备进行WPT的研究大多都是线圈正对,并且发射线圈和接收线圈的中心位置基本没有偏移的情况。本文设计了一种对旋转轴进行侧向无线供电的WPT系统,建立了单发射端和多接收端的模型并进行了理论分析,然后用COMSOL软件对模型进行仿真分析,改变发射端和接收端线圈的数目,计算传输效率等参数。仿真和实验结果表明,当两个发射线圈间隔135°排布,4个接收线圈间隔90°排布时,系统传输效率与输出功率波动最平稳,系统输出功率为6.0~6.8 W,传输效率为60%~70%。
Magnetic coupling resonance wireless power transfer(MCR-WPT)has been a hot research topic in recent years,and how to carry out WPT for rotating equipment has become a new hot topic when static research has been satu⁃rated.At present,most of the research on WPT of rotating equipment is when the coils are aligned,and the center posi⁃tions of the transmitting coil and the receiving coil are basically not offset.In this paper,a WPT system for lateral wire⁃less power supply on the rotating axis is designed,a model of single transmitter and multiple receivers is established and analyzed theoretically,and then the model is simulated and analyzed by COMSOL software,the number of transmitter and receiver coils is varied,and the transmission efficiency and other parameters are calculated.The simulation and experimental results show that when the two transmitter coils are arranged at 135°apart and the four receiver coils are arranged at 90°apart,the transmission efficiency and output power fluctuation of the system are the most stable,the system output power is 6.0~6.8 W,and the transmission efficiency is 60%~70%.
