Abstract

A horizontal patterned magnetic flux inductor system includes a magnetic inductor core that defines a longitudinal gap passing through the core volume in a vertical direction. The inductor core forms a three-dimensional flux path around the longitudinal gap whose projection onto the x-z plane forms a figure eight pattern with its two lobes oriented in the x direction. First and second electrical conductors are spaced apart in the x direction and pass through the core volume and through the longitudinal gap such that the inductor core causes inverse coupling between the conductors when electric current flows through the conductors in the same direction but causes positive coupling between the conductors when electric current flows through the conductors in opposite directions. Each of the electrical conductors has a front end exposed at the front side of the core volume and a back end exposed at the back side of the core volume.

Dependent claims

A horizontal patterned magnetic flux inductor system, comprising:

a first inductor assembly that includes a magnetic inductor core, wherein the inductor core defines a core volume having a width from a left side to a right side of the core volume in an x direction, a length from a front side to a back side of the core volume in a y direction, and a depth from a top side to a bottom side of the core volume in a z direction, wherein the x, y, and z directions are mutually orthogonal, the x and the y directions correspond to a horizontal dimension, and the z direction corresponds to a vertical dimension;
wherein the inductor core defines a longitudinal gap that passes through the core volume in the z direction;
wherein the inductor core forms a three-dimensional flux path around the longitudinal gap whose projection onto the x-z plane forms a figure eight pattern with its two lobes oriented in the x direction;
and
further comprising first and second electrical conductors spaced apart in the x direction and passing through the core volume and through the longitudinal gap such that the inductor core causes inverse coupling between the conductors when electric current flows through the conductors in the same direction but causes positive coupling between the conductors when electric current flows through the conductors in opposite directions;
wherein each of the first and the second electrical conductors has a front end exposed at the front side of the core volume and a back end exposed at the back side of the core volume, and wherein at least one of the ends comprises a vertical extension reaching to the bottom plane of the core volume such that the front end and the back end are each operable to make electrical contact with one or more additional components disposed at or below the bottom plane of the core volume.

further comprising first and second electrical conductors spaced apart in the x direction and passing through the core volume and through the longitudinal gap such that the inductor core causes inverse coupling between the conductors when electric current flows through the conductors in the same direction but causes positive coupling between the conductors when electric current flows through the conductors in opposite directions;
