- Abstract
- In this paper, two methods for calculating the maximum efficiency of the wireless power transfer system with multiple relays are presented. One method utilizes the ABCD matrix of two-port network by ignoring the non-adjacent couplings. To improve the accuracy of the analysis, the other method takes into account the non-adjacent couplings between the resonators. The program based on circuit equations is coded by MATLAB. As expected, the method including the non-adjacent couplings gives rise to more accurate result. From the parametric study regarding the number of couplings, at least one non-adjacent coupling should be considered to predict the maximum efficiency and the shifted frequency of the WPT system with relays adequately.
