ABSTRACT:
A cryogenically cooled circuit, operating at temperatures at which inductors windings of the circuit exhibit superconducting characteristics, provides unique advantages in high performance, preferably high power circuits. The entire circuit, as opposed to for example only the superconducting portions of the circuit, are refrigerated to cryogenic temperatures. Advantages in the characteristics of not only the superconducting based components but also the diodes, and gating elements such as MOSFET's, yield a uniquely advantageous circuit enabling the operation of, for example, a switching power supply at lower frequency using larger inductor values. The refrigeration penalty is overcome at power outputs on the order of 50 kilowatts while and equally important, size, component count, and stability benefits are attained by cryogenically cooling the entire circuit configuration.
