To improve the power transfer efficiency of electric resonance coupling wireless power transfer (ERC-WPT), it is necessary to improve the quality factor of the resonator. However, there is a limit to the improvement of the quality factor of resonators using copper wire. To overcome this problem, we designed the high quality factor resonator with superconducting wire, and confirmed by simulation how much the power transfer efficiency of the ERC-WPT using it is improved compared to that using a copper resonator. This is the first study using superconducting wires for ERC-WPT.
