Wireless Power Transmission Model and Experimental Device

首先从耦合模型理论的角度分析了系统的传输效率,得到了线圈天线的参数与效率之间的关系,从而可以有目的地进行天线的调谐,以达到最好的传输效果。然后根据理论结果来进行实验的构建,通过对实验结果的分析,验证了理论的正确性和可行性。理论分析和实验结果均表明天线自身的电感和电阻值对效率都有很大影响。最后,结合理论分析的结果,通过实验的调试,提出了改进的思路和方法,并且做出了合理的推断和验证,对未来的工作有一定的指导意义。

Transmitter and receiver coil antennas with high quality factor are the most important part of wireless energy transfer model. The transmission efficiency of the system was analyzed from the perspective of coupled mode theory ; and the relationship between parameters of coil antennas and the efficiency was obtained, which can tune the antennas purposefully to achieve the best transmission. Then, an experimental apparatus based on the theoretical resuks was built, which verified the correctness and feasibility of the theory. Theoretical analysis and experimental results show that the inductance and resistance value of the antenna itself has an important influence on efficiency. Finally ,with the results of theoretical analysis and experiment debugging, ideas and methods for improvement were proposed, and a reasonable inference and validation were conducted. This is a perfect guidance for future work.
