Abstract
In this paper, characteristics of a heater-triggered switching system for the charging of Bi-2223 double pancake load with 1.7 mH has been analyzed through the simulations and experiments. Two heaters were used to store the energy in high-Tc superconducting (HTS) load. The timing of the sequential control and the heating current with two heaters are important factors to generate pumping-current. The thermal analysis of the switch considering the heater input and time was carried out. Based on the analysis just mentioned, heater-triggered switch was fabricated. Characteristic analysis was carried out through two modes having different sequential timing controls. Maximum current stored in the HIS load reached 18 A and the pumping rate was 113 mA/s at that time.
