The low efficiency of wireless power transfer is an important issue that restricts its application. Superconducting wireless power transfer is more efficient than conventional wireless transmission. To further improve the superconducting wireless power transfer efficiency and optimize its characteristics, this paper studied the superconducting wireless power transfer impedance matching. The impedance of superconducting wireless power transfer was analyzed, which illustrated the necessity of impedance matching optimizing characteristics for superconducting wireless power transfer. Fixed frequency and distance, impedance matching design for superconducting wireless power transfer, and impedance matching experimental device were built to verify that impedance matching was an effective means to improve the superconducting wireless power transfer efficiency. It could provide a useful reference for the study of adaptive impedance matching for superconducting wireless power transfer.
