  • Patent number: 12381035
    Abstract: According to one configuration, a fabricator fabricates a core of a circuit component to include magnetic permeable material. The fabricator further produces the circuit component to include multiple electrically conductive paths extending through the core of the magnetic permeable material. In one arrangement, the multiple electrically conductive paths include a first electrically conductive path and a second electrically conductive path. The fabricator fabricates the circuit component and, more specifically, the core of the magnetic permeable material to include at least one cutaway portion operative to reduce inductive coupling between the first electrically conductive path and the second electrically conductive path disposed in the core.

  • Patent number: 12166416
    Abstract: A power supply includes a first (main) power converter and a second (auxiliary) power converter disposed in parallel with the first power converter to produce an output voltage to power a dynamic load. The second power converter includes a primary inductive path magnetically coupled to a secondary inductive path. A controller controls a flow of first current through the primary inductive path of the second power converter to control flow of second current supplied by the secondary inductive path to the dynamic load. During steady state conditions, the first power converter produces the output voltage while the second power converter is deactivated. During transient load conditions, the second power converter provides current boost capability to maintain a magnitude of the output voltage within a desired range.

  • Patent number: 12088205
    Abstract: According to one configuration, an inductor device comprises: core material and one or more electrically conductive paths. The core material is magnetically permeable and surrounds (envelops) the one or more electrically conductive paths. Each of the electrically conductive paths extends through the core material of the inductor device from a first end of the inductor device to a second end of the inductor device. The magnetically permeable core material is operative to confine (guide, carry, convey, localize, etc.) respective magnetic flux generated from current flowing through a respective electrically conductive path. The core material stores the magnetic flux energy (i.e., first magnetic flux) generated from the current flowing through the first electrically conductive path.
