Patent ID: 7019608

Claim:
A superconducting transformer, comprising: a first primary winding for electrically connecting with an alternating power source, and having a first plurality of turns of superconducting tape; a second primary winding for electrically connecting with the source and having a second plurality of turns of superconducting tape; a first secondary winding for electrically connecting with a load, the first secondary winding magnetically coupled to the first primary winding and having a third plurality of turns of superconducting tape; a second secondary winding for electrically connecting with the load, the second secondary winding magnetically coupled to the second primary winding and having a fourth plurality of turns of superconducting tape; a sheath surrounding all of the windings; and wherein the first primary winding, the second primary winding, the first secondary winding, and the second secondary winding are concentrically nested; and wherein each respective winding is comprised of a twisted filament superconductor having one or more filaments.
