Claims
- 1. A transformer having a magnetic yoke and at least a first electric turn and at least a second electric turn, wherein the improvement comprises that the transformer is composed of a plurality of thin-film layers, a first magnetically permeable layer and a second magnetically permeable layer together forming a magnetic yoke within which the turns formed from electrically conducting layers extend, and in which a layer of a superconducting material is provided between the turns and portion of the magnetic yoke.
- 2. A transformer as claimed in claim 1, wherein the electrically conducting layers also comprise a superconducting material.
- 3. A transformer having a magnetic yoke and at least a first electric turn and at least a second electric turn, wherein the improvement comprises that the transformer is composed of a plurality of thin-film layers, a first magnetically permeable layer and a second magnetically permeable layer together forming a magnetic yoke within which the turns formed from electrically conducting layers of a superconducting material extend, and in which, at least within the magnetic yoke, the distance between the juxtaposed turns of superconducting material being small in comparison to the widths of the layers of separate turns.
- 4. A transformer formed of thin-film layers comprising:
- first and second magnetically permeable layers forming a magnetic yoke;
- at least one primary turn of electrically conducting material disposed between said first and second layers of magnetically permeable material;
- at least one secondary turn of electrically conducting material disposed between said first and second layers of magnetically permeable material; and
- a layer of superconducting material disposed between one of said primary and second turns and at least one of said first and second layers of magnetically permeable material.
- 5. The transformer as claimed in claim 4, wherein at least one of said primary and secondary turns comprise superconducting material.
- 6. The transformer as claimed in claim 4 in which at least one of said primary and secondary turns have a width and the distance between adjacent turns is less than said width of the turns.
