1Abstract
A single-phase, thermally switched superconducting power converter operating at mains frequency is being developed and tested by the authors. Typical design values of the device are: input voltage of 220 V; input current of 7 A; output voltage of 1 V; and output current of 1 kA. The average output power is about 750 VA, with an efficiency better than 96%. Test results of the full scale power converter while ramping up and down a superconducting magnet and a comparison with the theory are presented. The power converter will be installed as a part of a power supply system controlling the current of a separator magnet located in Ukraine for an iron ore recycling process
