Patent ID: 8130069

Claim:
An electrical system, comprising: an inductor, comprising: an inductor core, said inductor core comprising: a plurality of coated particles, each of a majority of said coated particles comprising: at least three layers; a first set of alternating substantially magnetic layers, wherein said magnetic layers comprise at least one alloy; and a second set of alternating substantially non-magnetic layers, said coated particles about evenly distributed in at least a portion of said inductor core; and a winding about at least a section of said inductor, said winding configured to transmit a current of at least forty amperes, the current comprising a frequency component of at least five hundred hertz, said inductor configured to carry a magnetic field of at least one of: less than about 3,500 Gauss at an absolute Oersted value of at least 100; less than about 7,000 Gauss at an absolute Oersted value of at least 200; less than about 10,500 Gauss at an absolute Oersted value of at least 300; and less than about 14,000 Gauss at an absolute Oersted value of at least 400.
