Persistent Mode Current Switches (PMCS) are made from coils of superconductor that in theory will provide zero conduction losses when closed. By causing a section of the superconductor to leave its superconducting state and become resistive, the switch is effectively opened. There are currently 3 methods to open a PMCS; 1) applying heat, 2) applying a magnetic field or 3) application of current above the critical current (Ic) of the tape. The first two methods are not suitable for power applications as the switching time is too slow. Recent work at the University of Wollongong and in literature has shown …

The University of Wollongong (UoW) has received funding for the research and development of a high transition temperature (HTS) superconducting magnetic energy storage (SMES) device designed to operate at 40 K. This paper provides an update on work previously reported at AUPEC (2001) and summarises progress in the areas of computer assisted modelling, electromagnetic and thermal coil design, electronic control system, current leads and the cryogenic system. The proposed coil design for the SMES will be evaluated and discussed with respect to its advantages and limitations.
