Abstract

Methods for forming a high current inductor leverage solid core materials to form ribbon inductors. In some embodiments, the method may include forming a central opening lengthwise through a solid core conductive material, wherein the solid core conductive material has an outer diameter, the central opening forms an inner diameter of the solid core conductive material, and a difference between the outer diameter and the inner diameter is a thickness of a ribbon conductor of the high current inductor and removing a spiral portion of the solid core conductive material to form the ribbon conductor of the high current inductor, wherein a width of the spiral portion forms a gap spacing between windings of the ribbon conductor.

A method for forming a high current inductor, comprising:

forming a central opening lengthwise through a conductive material with a solid core, wherein the conductive material has an outer diameter, the central opening forms an inner diameter of the conductive material, and a difference between the outer diameter and the inner diameter is a thickness of a ribbon conductor of the high current inductor;
and
removing a spiral portion of the conductive material to form a continuous spiral gap for an entire length of the conductive material, wherein a remaining portion of the conductive material forms the ribbon conductor in a shape of a helix of the high current inductor, wherein a width of the spiral portion forms a gap spacing between windings of the ribbon conductor, and wherein the high current inductor is configured to conduct at least 200 amps of current.
