Abstract

This paper studies the efficiency and load characteristics of the superconducting wireless power transfer system (HTS-WPT). Mathematical modeling of the power and efficiency of different parts and the overall HTS-WPT system is deduced. Factors that affect system overall efficiency are identified. Specially, the impact of ac power loss of superconductor on system overall efficiency is studied. An optimal operating zone (OOZ) of the HTS-WPT is proposed to achieve optimal power and efficiency for the HTS-WPT. The OOZ provides guidance for designing the operating points of an HTS-WPT. The results of the modeling are confirmed by an experimental down-sized HTS-WPT system.
