Characterisation of superconducting components using PSPICE

A customer library of superconducting (SC) components for the PSPICE is under development in our group. The new library includes models of both low and high T/sub c/ superconductor based components. For large scale applications typical examples of simulated components are: a SC filament, composite wire and tape, a cable, a magnet, a switch, a transformer, a rectifier. Each model can he easily customised for a particular application. When the scheme is ready, it can he analysed using the powerful tools offered by PSPICE. The current status of the theory and model development and a few typical examples together with brief review of the practical conductors are presented and discussed in the paper.
