Summary

The superconductor simulator is an electronic circuit that emulates the extremely nonlinear voltage-current characteristics (the basis of a critical-current measurement) of a superconductor along with its other major electrical properties. Three different types of simulators have been constructed: the passive, active and hybrid simulator. Design, characteristics, and applications of the superconductor simulator along with a summary of features are presented. The 50 A simulator provides critical-current precision of 0.1% at a microvolt signal. This is significantly higher than the precision of a superconducting standard reference material. The superconductor simulator could significantly benefit superconductor measurement applications that require high-precision quality assurance.
