Abstract

This paper presents the results of experimental studies of switching processes of high-temperature superconducting tapes under the action of microsecond duration pulsed current loads. Reversible, stable and irreversible switching of the superconductor to the normal state has been realized. To demonstrate the possibility of implementing controlled generation of transient processes in superconducting composites, based on experimental results, the characteristics of a superconducting switch capable of switching between different types of terminal excitations, in particular the possibility of simultaneous power cutoff in current and voltage, were calculated.

Keywords: dynamic states; HTS switch; HTS commutator
