Abstract
The invention comprises an apparatus, comprising: a toroid shaped inductor and a cooling jacket including at least two sections joined to encase the toroid shaped inductor, where the cooling jacket has an inner toroid shaped surface separated by a coolant flow gap from the toroid shaped inductor. Optionally, the inductor comprises a cast winding, a cast heat sink element of the cast winding protruding from a longitudinal length of a turn of the winding, and/or a distributed gap pressed powder inductor core.
Claims4
An apparatus, comprising:
- a toroid shaped inductor, said toroid shaped inductor comprising:
- an inductor core, said inductor core comprising:
- a plurality of coated particles comprising an average particle size of less than one hundred micrometers, each of a majority of said coated particles comprising:
- at least three layers;
- a first set of alternating substantially magnetic layers;
- and
- a second set of alternating substantially non-magnetic layers,
- an inductor winding about at least a section of said inductor core, said winding configured to transmit a current of at least fifty amperes,
- said toroid shaped inductor configured to carry a magnetic field of less than 7,000 Gauss at an absolute Oersted value of at least 200,
- said coated particles about evenly distributed in at least a portion of said inductor core;
- and
- a cooling jacket, said cooling jacket comprising at least two sections, wherein said at least two sections of said cooling jacket join to encase said toroid shaped inductor.
