    摘要： Disclosed are apparatus and methods for arrayed embedded magnetic components that include magnetic devices that have a core that is embedded between two or more substrates and a winding pattern surrounding the core that is implemented on and through the two or more substrates. The winding pattern is operable to induce a magnetic flux within the core when energized by a time varying voltage potential. The winding pattern may be implemented by printed circuit layers, plated vias, other electrically conductive elements, and combinations thereof. Arrayed embedded magnetic components include two or more electrically interconnected magnetic devices positioned side-by-side in a horizontal integration, positioned top-to-bottom in a vertical integration, or combinations thereof. The magnetic devices may have a magnetic functionality such as, but not limited to, a transformer, inductor, and filter. Disclosed magnetic components and methods provide for low cost construction, consistent performance, and a low profile form, among other benefits.

    摘要： Disclosed are apparatus and methods for embedded high voltage transformer components. Industrial applications require transformers that provide high voltage isolation. The laminate materials used for fabricating Printed Circuit Boards (PCB) are very good insulators and PCB transformers can provide higher voltage isolation than traditional wire wound devices. There are a variety of PCB laminate materials with different properties for voltage breakdown. FR-4 laminate is commonly used and has voltage breakdown properties exceeding 10 kV/mm. To produce PCB transformers with breakdown voltages exceeding 5 kV, it is beneficial to use laminate with much higher breakdown voltages. Generally, the materials with high breakdown voltage cost more. High voltage isolation can be achieved at a moderate cost by mixing low cost FR-4 laminate with high voltage dielectric materials.

    摘要： A method for gapping a magnetic component is disclosed. The method includes: forming a feature on a substrate, the feature being a depression defining an inside surface; disposing a first conductive pattern on the substrate and the inside surface of the feature; disposing a permeability material on the inside surface of the feature and the first conductive pattern; disposing a substrate material on the substrate and the feature; disposing a second conductive pattern on the substrate material to wrap the permeability material between the first conductive pattern and the second conductive pattern to define at least one electrical circuit to facilitate a magnetic field in the permeability material; and gapping the permeability material to remove at least a portion of the permeability material to produce a gap in the at least a portion of the permeability material.

    摘要： Disclosed are apparatus and methods for a magnetic component. In accordance with an embodiment, a magnetic component comprises a base substrate defining a winding cup having a shape of a closed groove surrounding a hub. The winding cup defines a core space operable to receive a core therein. A first conductive pattern is disposed on at least a portion of the base substrate including the winding cup. A second substrate defines a second conductive pattern. The second substrate is coupled to the first base surface with the first conductive pattern in operable alignment with the second conductive pattern. The first and second conductive patterns are coupled in electrical communication so as to define one or more winding-type electric circuits surrounding the core space so as to induce a magnetic flux within the core space when the one or more electric circuits are energized by a voltage source.
