Abstract: The invention comprises an apparatus, comprising: an inductor, comprising: an inductor core and a winding comprising a wound shape around the inductor core, where the winding comprises a first cross-sectional area at a first longitudinal position along the winding and a second cross-sectional area at a second longitudinal position along the winding, the second cross-sectional area at least twenty percent larger than the first cross-sectional area. Optionally and preferably, the winding includes a first set of cast elements sharing a first geometric shape and a second set of cast elements sharing a second geometric shape, where the alternating members of the first set of cast elements and the second set of cast elements are welded together to form the winding.

Abstract: The invention comprises an apparatus, comprising an inductor, the inductor comprising: an inductor core; a first winding section comprising a first cast shape and a second winding section comprising the first cast shape, the first winding section mechanically joined to the second winding section to form a winding, the winding forming a wound shape about the inductor core. Optionally and preferably, a third winding section, comprising a second cast shape, mechanically joins the first winding section to the second winding section and a mechanical connector and/or an aluminum weld join the first winding section to the third winding section.

Abstract: The invention comprises a method, including the steps of: providing an inductor core and longitudinally joining a first electrical turn section to a second electrical turn section to form at least part of an electrical turn of a winding about the inductor core and optionally including at least one of the steps of: (1) additive manufacturing, casting, stamping from metal stock, cutting material, and/or bending metal to form the first electrical turn section and/or (2) welding and/or mechanically joining the first electrical turn section to the second electrical turn section.

Abstract: The invention comprises a method for forming an inductor, comprising the steps of: providing an inductor core and fastening at least ten sections of a winding together to form a winding, the winding comprising a formed wound shape about the inductor core. Optionally and preferably the step of fastening repeats steps of joining a member of a first set of winding parts to an element of a second set of winding parts, where the two sets of winding parts have different cast or formed shapes.

Abstract: The invention comprises a method of: providing an inductor core, placing a winding guide within an inch of the inductor core, positioning a first turn element with the winding guide, positioning a second turn element with the winding guide, and mechanically coupling the first turn element to the second turn element to form at least a part of a winding, the winding forming a wrapped shape about the inductor core. Optionally and preferably, turn elements are subsequently joined, mechanically coupled, and/or welded together to form sections of the winding.

Abstract: The invention comprises an apparatus, comprising: an inductor, the inductor comprising: an electrical turn about an inductor core, the inductor core comprising a ring shape; the electrical turn comprising a first width at a first radial distance from a center of the inductor core and a second width at a second radial distance from the center, the second width at least ten percent larger than the first width. Optionally and preferably, the electrical turn comprises: a first cast element and a second cast element and a mechanical connection connecting the first cast element to the second cast element, such as an aluminum weld.

Abstract: The invention comprises a multi-inductor mounting/cooling apparatus and method of use thereof comprising: an elongated tube having a first elongated section and a second elongated section separated by at least a first longitudinal split down a length of the elongated tube and at least three inductors affixed to a baseplate, the at least three inductors positioned within the elongated tube, the at least three inductors comprising a plurality of connectors extending radially outward through at least one aperture formed between the first elongated section and the second elongated section. Optionally and preferably a fan is positioned within and/or at an end of the elongated tube.
