摘要
我们开发了一种低温冷却器系统，以揭示高温超导（HTS）线圈质量（Q）因子的温度依赖性，以及使用 HTS 线圈的无线功率传输（WPT）系统的功率传输效率（PTE）和功率处理能力（PHC）。在 77 K 时，HTS 大体积线圈的测量 Q 值为 9051，在 25 K 时为 14 050；在 77 K 时，WPT 系统的测量 PTE 和 PHC 分别为 44.2% 和 4.48 W，在 25 K 时分别为 50.8% 和 25.2 W。
Temperature dependence of power transfer efficiency and power handling capability of wireless power transfer system using superconducting bulk coil
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.
