Analysis of Efficiency Characteristics of Superconducting Coil-Applied Wireless Power Transmission Systems by Transmission Distance

A significant amount of research is being done on the commercialization of magnetic-resonance-based wireless power transmission. To this end, research on boosting transmission efficiency is essential. In this paper, a wireless power transmission system was designed using superconducting coils to boost wireless power transmission efficiency. The efficiency of a normal wireless power transmission system and a superconducting wireless power transmission system was calculated according to the transmission distance. Results confirmed that compared to the use of the ordinary conducting coil, the use of superconducting coil offered higher transmission efficiency at a farther distance.
