<p>A cryogenically cooled circuit (10), operating at temperatures at which inductor windings of the circuit (10) exhibit superconducting characteristics, provides unique advantages in high performance, preferably high power circuits. The entire circuit (10) is cryogenically cooled in a compartment (16) in a refrigeration device (12). The cryogenically cooling of all the components of the circuit (10) such as diodes and gating elements (MOSFET's) yields a circuit which enables the operation of a power switching supply at a lower frequency using large inductor values. The refrigeration penalty is overcome with power outputs on the order of 50 kilowatts while, and equally importantly, size, component count and stability benefits are attained by cryogenically cooling the entire circuit configuration.</p> |
