  • Publication number: 20220013276
    Abstract: According to one configuration, an inductor device comprises core material and at least a first electrically conductive path. The core material is fabricated from magnetically permeable material. The first electrically conductive path extends axially through the core material from a proximal end of the inductor device to a distal end of the inductor device. The core material is operable to confine first magnetic flux generated from first current flowing through the first electrically conductive path. The inductor device further includes a gap in the core material. The gap (gas or solid material) has a different magnetic permeability than the core material. Inclusion of the gap in the core material provides a way to tune an inductance of the inductor device and increase a magnetic saturation level of the inductor device. The core material includes any number of electrically conductive paths and corresponding gaps.

  • Patent number: 10707765
    Abstract: A power converter circuit includes a transformer. The transformer includes a primary winding and a secondary winding. A primary circuit is coupled to the primary winding. A secondary circuit is coupled to the secondary winding. The primary circuit and the secondary circuit are referenced to different ground voltage potentials that may vary with respect to each other. During operation, the primary circuit controls input of energy to the primary winding of the transformer. The secondary circuit receives the energy through the secondary winding and uses it to produce an output voltage to power a load. The secondary circuit receives and/or generates state information at one of multiple different levels. The secondary circuit controls a flow of current through the secondary winding to convey the state information as feedback to the primary circuit. The primary circuit analyzes a voltage at a node of the primary winding to receive the feedback.
