Abstract

This study is based on resonant wireless power transfer with the type of series to series (S-S) in hope to discuss the status and simplified particular solutions of dual antennas for transmission. The Concentric Flat - Plate (CFP) antenna is used in this study and interaction of electromagnetic waves during transmission makes it difficult to predict the reception result. Analyzing the interaction of two electromagnetic waves during transmission makes it easy to predict the reception result also understand the transmission mechanism clearly. Complex mathematical equations require computer simulations to produce results but solve the analytical solution using in time domain's method. The solutions in this paper can precisely prediction the attenuation using in WPT system based on specific signal frequency working at 13.56 MHz which is included in ISM band. The working frequency is set to the resonant frequency. The result is very useful in WPT system with the result. Compared the results with simulation to demonstrate the solution.

13.56 MHz无线电力传输中近场谐振传输的瞬态分析及其简化特解

本研究基于串联到串联(S-S)类型的谐振无线电力传输，希望探讨双天线传输的现状及简化特解。本研究采用同心平板(CFP)天线，由于电磁波在传输过程中的相互作用，使得接收结果难以预测。分析两种电磁波在传输过程中的相互作用，既便于预测接收效果，又能清楚地了解传输机理。复杂的数学方程需要计算机模拟才能得到结果，而解析解的求解则采用时域方法。本文的解决方案可以根据ISM频段13.56 MHz的特定信号频率精确预测WPT系统中使用的衰减。将工作频率设置为谐振频率。该结果在WPT系统中非常有用。将计算结果与仿真结果进行比较，验证了该方法的有效性。
