Abstract

A review is given of several known thermally controlled switches developed for superconducting converters. It shows their rather low frequency of operation (up to a few Hz) which strongly differs from the industrial frequency. This is not only due to the long recovery times of the switches, but also to the fact that the efficiency drops as the frequency increases. To develop switches suitable for 50 Hz, having reasonable efficiency, a theoretical model of the switch is necessary. Such a model is presented here, and illustrated for 50 Hz switches made from NbTi foil.
