摘要
目前,磁谐振式无线电能传输(Magnetic coupling resonance-wireless power transmission,MCR-WPT)的研究主要集中于静止状态下的双发射单负载和三发射单负载系统.本文对双发射多负载低速转动系统进行了研究,通过建立双发射多负载系统的理论模型,结合COMSOL软件进行仿真,并搭建接收端转动的二维全向磁谐振式无线电能传输实验平台,验证了正交发射线圈不同相位差、不同接收线圈数量及线圈相对位置改变对转动系统能量传输效率的影响.结果表明,当正交双发射线圈存在90°相位差时,系统在接收端线圈固定距离内能够维持稳定的磁场传输特性,随着负载线圈数量的增加,系统的总传输效率波动幅度有所改变,当负载为4个时波动最小.
Abstract
Currently,research on magnetic coupling resonance-wireless power transmission(MCR-WPT)primarily concentrates on dual-transmitter single-load and triple-transmitter single-load systems in a stationary state.This article explores the dual-transmitter multi-load low-speed rotating system.By establishing a theoretical model for the dual-transmitter multi-load system and utilizing COMSOL software for simulation,we have constructed a two-dimensional omnidirectional magnetic resonance wireless energy transmission experimental platform for the rotating receiving end.This platform allows us to verify the impact of various factors on the energy transmission efficiency of the rotating system,including different phase differences of orthogonal transmitting coils,varying numbers of receiving coils and alterations in coil relative positions.The results indicate that when there is a 90° phase difference between the orthogonal dual-transmitter coils,the system can maintain stable magnetic field transmission characteristics within a fixed distance from the receiving coil.As the number of load coils increases,the fluctuation range of the system's overall transmission efficiency changes.Notably,the fluctuation is minimal when there are four load coils.
