| description | This study analyses the wireless power transfer of the resonance-based magnetic coupling method and resonance-based electric coupling method and provides information about the characteristics of each. To compare the characteristics of each method, the power transfer efficiency was analysed according to the transfer alignment and misalignment distance between the transceivers. More specifically, they were theoretically analysed through equivalent circuit models, and the results were verified through electromagnetic numerical analysis simulation and the fabrication and experimental results of a wireless power transfer coupler. Although both methods differ according to the coupling method, in terms of power transfer efficiency, it was found that they are determined by the same physical phenomena. Furthermore, in both methods, a null-power point occurred during misalignment between the transceivers. The misalignment distance within which the null-power point occurred is intrinsically determined by the structure of the resonant coupler. |
