Abstract
A transformer is provided that includes a plurality of metal lines and a magnetic material provided about the plurality of metal lines. The magnetic material may include a structure to reduce Eddy currents flowing in the magnetic material. This structure may be a plurality of slots extending perpendicular to the metal lines. This structure may also be a laminated structure.
Claims26
A transformer comprising:
- a plurality of parallel metal lines;
- and
- a magnetic material provided about the plurality of parallel metal lines, the magnetic material including a structure to reduce Eddy currents flowing in the magnetic material, the structure including a plurality of parallel slots provided in the magnetic material, the plurality of parallel slots extending substantially perpendicular to the plurality of parallel metal lines.
A transformer comprising:
- a plurality of parallel metal lines of the transformer;
- and
- a magnetic material provided about the plurality of parallel metal lines, the magnetic material including a structure to reduce Eddy currents flowing in the magnetic material, the structure including a laminated magnetic structure having layers of magnetic material and insulation material.
A transformer comprising:
- a plurality of metal lines of the transformer formed substantially parallel to each other;
- insulative material to surround the plurality of metal lines;
- magnetic material to surround the plurality of metal lines;
- and
- a plurality of slots formed on the magnetic material, the slots formed substantially perpendicular to the plurality of metal lines of the transformer.
