Abstract

This paper presents the design and fabrication of a high-Tc superconducting (HTS) power supply. Its characteristics have been analyzed through experiments. A HTS power supply consists of two heaters, an electromagnet, and a Bi-2223 solenoid and a Bi-2223 pancake load. The timing sequential control of two heaters and an electromagnet is an important factor to generate pumping-current in the Bi-2223 load. The thermal analysis of switching parts of the Bi-2223 solenoid according to the heater input was carried out. Based upon the analysis, the 331 mH electromagnet and the 0.8 A dc heater current were optimally derived, and 8.5 sec and 17 sec for the pumping period were selected in this experiment. In the experiment, the maximum pumping current reached 1.7 A.
