Abstract

This paper deals with the design and fabrication of a heater-trigged high-Tc superconducting (HTS) power supply. Its characteristics have been analyzed through experiments. A heater-trigged HTS power supply consists of two heaters, an electromagnet, and a YBCO bulk superconductor. The timing sequential control of two heaters and an electromagnet is an important factor to generate pumping-current in the bulk YBCO superconductor. The thermal analysis of switching parts of the YBCO superconductor according to the heater input was carried out. Based upon the analysis, the 0.6 T electromagnet and the 2.3 A dc heater current were optimally derived, and 190 sec and 380 sec for the pumping period were selected in this experiment. In the experiment, the maximum pumping current reached about 12 A.
