| Abstract(in English) | In this study, we proposed the method that decrease the resonant frequency (f0) of high temperature superconductor (HTS) bulk coil by the thickness of sapphire substrates which supported HTS bulk coil because there is limit to diameter of HTS bulk. We fabricated HTS bulk coil (coil diameter of 65 mm) which optimized line width and line gap of coil. The measured quality factor of it was 9,431, this was 12 times higher than that of copper coil. Moreover, at distance between coils of 20 cm, a power transfer efficiency of wireless power transfer (WPT) system using HTS bulk coil and copper coil as transmitting and receiving coil were 74.8% and 20.6%, respectively. As a result, we achieved high transfer efficiency WPT system using high quality factor HTS bulk coil. |
