Abstract
The invention is an inductive device featuring very low losses even in circuits which supply more than about 10 kilowatts of power. The device includes an inductor comprising a core consisting primarily of a highly permeable magnetic material and at least one winding of a high temperature superconducting conductor contained substantially within the core and in spaced relation with respect to the core sufficient to maintain its electrical integrity, refrigeration means for cryogenically cooling at least the conductor winding portion of the inductor to a temperature at which each conductor winding exhibits superconductivity, and input/output means for providing power to and receiving power from each conductor winding. Also disclosed are a balancing choke and a circuit embodying a common mode inductor made in accordance with the invention.
