Influence of the Current Distribution in Superconducting Resonators for Wireless Power Transmission on the AC Loss Characteristics

Abstract

This paper investigates the AC loss characteristics in the resonator of the superconducting wireless power transmission system proposed by Prof. Sekiya. This superconducting resonator is characterized by the fact that the current distribution is not constant in the tape length, the REBCO tapes are double layered, and the operating frequency is 10 MHz. Since the influence of eddy current loss cannot be ignored due to the high operating frequency, we investigated the effect of the REBCO tape configuration using the finite element method.
