Theory and Verification Tests of the Nb-Ti Ribbon Thermally Controlled Switch for 50 Hz Applications
Theoretical analysis of the influence of the Nb-Ti ribbon thickness/ of the bath and working temperatures on the recovery time constant and the losses of a thermally controlled superconducting switch (TCSS) is presented. It reveals the possibility to increase the repetition frequency of such switch in the range of the industrial 50–60 Hz frequency. Successful verification tests of a thermally controlled switch made from 20 um thick, 10 mm wide and 11 cm long Nb-Ti ribbon in a half-wave rectifier mode at 50 Hz have been performed.
