Abstract
We developed a cryocooler system to reveal the temperature dependence of the quality (Q) factor of high-temperature superconducting (HTS) bulk coil and the power transfer efficiency (PTE) and power handling capability (PHC) of a wireless power transfer (WPT) system using the HTS bulk coil. The measured Q factors of the HTS bulk coil were 9051 at 77 K and 14 050 at 25 K. The measured PTEs and PHCs of the WPT system were 44.2% and 4.48 W at 77 K, and 50.8% and 25.2 W at 25 K.
