Abstract
The invention provides a variable impedance device including a first bus bar refrigeration system, a first bus bar thermally connected to the first bus bar refrigeration system to be maintained at a target bus bar temperature by the first bus bar refrigeration system, a variable impedance component refrigeration system, a variable impedance component electrically connected to the first bus bar and thermally connected to the component refrigeration system, a variable impedance component may be at least partially made of a material that is superconducting below a critical temperature and may be maintained at a target component temperature, wherein the target bus bar temperature may be between the 300K and critical temperature and the target component temperature may be below the critical temperature and a second bus bar connected to the variable impedance component so that current flows between the first and second leads through the variable impedance component.
