Research Abstract

Superconductivity (SC) has unique properties. One of them is zero resistance at SC state and its device can deliver large capacity of current essentially without Joule heat. Such specific feature is very attractive for a kind of inverters used as power devices. In order to develop the optimized SC inverter, a novel soft superconducting material and device has been proposed. It was made clear that the present SC device can be efficiently applied to the inverter for solar cell power generation.
