INDUCTOR APPARATUS AND METHOD OF MANUFACTURE THEREOF

摘要

The invention comprises an electrical apparatus and method of manufacture. The apparatus includes a substantially annular inductor comprising an inductor core composed of at least a distributed gap material. The distributed gap material includes particles of alternating layers of magnetic and non-magnetic materials separated by a gap material. The particles comprise an average layer thickness of less than about one hundred micrometers, where a majority of said layered particles comprise an average cross sectional size of less than about one millimeter. The inductor is cooled using at least one of: a thermally conductive potting material, a liquid coolant in direct contact with the inductor, a cooling line through the potting material or liquid coolant, and a chill coil in a container about the potting material and/or the liquid coolant.

主权项

1. An electrical apparatus, comprising:
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 particles, wherein each of said plurality of particles comprises at least four alternating layers, said alternating layers alternating between a magnetic material layer and a substantially non-magnetic material layer; andat least one of:
an inductor core coating substantially coating at least a portion of said inductor core;an inductor winding circumferentially wound about at least a portion of said inductor core; andan inductor winding coating substantially coating at least a portion of said inductor winding; and a liquid coolant directly contacting said inductor.
