  • Patent number: 10522279
    Abstract: 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.

  • Patent number: 10395820
    Abstract: A common mode choke coil according to one embodiment of the present invention includes a first coil conductor, a second coil conductor, and a third coil conductor. In the embodiment, the second coil conductor has a different shape than the first coil conductor and the third coil conductor. In the embodiment, the first coil conductor, the second coil conductor, and the third coil conductor extend parallel with each other in a first region in plan view as seen from an axial direction along the coil axis. In the embodiment, in the first region, when seen in a cross section cut along a plane including the coil axis, in an n-th turn, an arranging order of the first coil conductor, the second coil conductor, and the third coil conductor from an inner side in a radial direction thereof is inverted from that in an n+1th turn.

  • Patent number: 10388448
    Abstract: A multilayer coil component includes an element body including soft magnetic metal powders and a coil disposed in the element body. The coil includes a plurality of internal conductors electrically connected to each other. The plurality of internal conductors are separated from each other in a first direction and are adjacent to each other in the first direction. An average particle diameter of the soft magnetic metal powders located at an inner side of the coil when viewing from the first direction is larger than an average particle diameter of the soft magnetic metal powders located between the internal conductors adjacent to each other in the first direction.

  • Patent number: 10361024
    Abstract: A dry-type transformer core has an iron core with a number of limbs designed to be wrapped with a winding and interconnected by a number of magnetic yokes. The object is to produce a transformer of this type in a simple manner, which is especially well protected against corrosion. For that purpose, the dry-type transformer core includes a casing that is formed onto the iron core. The casing surrounds the iron core in a substantially flush manner.

  • Patent number: 10347409
    Abstract: 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.
