Patent ID: 8624696

Claim:
A method for manufacture of an electrical apparatus, comprising the steps of: providing a substantially annular inductor, said inductor comprising an inductor core comprising at least a distributed gap material, said distributed gap material comprising: a plurality of layered particles, a first set of layers of said layered particles comprising a substantially magnetic material, a second set of layers of said layered particles comprising a substantially non-magnetic material; and a gap material between said plurality of layered particles, said gap material forming an average distance between two adjacent particles, of said layered particles, of greater than zero micrometers and less than about ten micrometers, wherein a majority of said layered particles comprise an average layer thickness of less than about one hundred micrometers, and wherein a majority of said layered particles comprise an average cross sectional size of less than about one millimeter; rotating said inductor; winding said inductor as a function of rotation of said inductor with multiple strands of wire; electrically connecting said strands of wire in parallel to form a winding; placing said inductor into a container; and positioning cooling means adjacent said inductor.
