【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。
[Abstract]:In recent years, more and more attention has been paid to various kinds of systems based on radio energy transmission technology. Most of the research on magnetic coupling resonant radio energy transmission technology focuses on the energy transmission in free space. In this paper, the possible encounter of metal dielectric obstacles in radio energy transmission systems is discussed. The obstacles are placed on the side of the transmitter, the side of the receiver and between the transmitter and receiver respectively. The simulation results show that the setting of metal obstacles has obvious influence on the magnetic field near the system, which is consistent with the experimental results. And it is proved that the adjustable capacitance can be adjusted. The output power of the system can be roughly restored to the same level as when there were no obstacles.
