摘要
近年来,基于无线电能传输技术的各类系统受到越来越广泛的关注。大多数关于磁耦合谐振式无线电能传输技术的研究集中于能量在自由空间中传播的情况,本文针对无线电能传输系统可能遇到金属介质障碍物的情况进行了探讨。分别将障碍物置于发射端一侧、接收端一侧以及发射端和接收端之间,并对其进行仿真分析及实验验证。仿真结果显示金属障碍物的设置对系统附近磁场有明显影响,与实验结果一致。并且证明,通过调节可调电容,可以使系统输出功率大致恢复到无障碍物时的水平。
There are various systems that based on the wireless power transmission （WPT） technology getting more attention in last few years.For recently,most researches are relative to magnetically coupled resonant WPT （MCR-WPT） technology converge on the power transmission in free space.That essay its focus on discusses the situations that metal dielectric obstacles may be encountered.It is separate to the transmitter side,the receiver side and between the transmitter and receiver,and the simulation analysis and experimental verification are done.The simulation results that after analysis,it is match with the experimental results that the metal barrier setting on system has significant effect on the magnetic field.It is proved that the system output power can make generally restored to the level when no obstacle by adjusting the adjustable capacitance.
