  • Patent number: 8164406
    Abstract: A transformer is provided. The transformer includes a first electrical conductor, a second electrical conductor, a circuit board and a core set. The first electrical conductor has a through hole and the second electrical conductor is electromagnetically coupled with the first electrical conductor and includes a plurality of spiral coils formed by winding a single conductive wire, each spiral coil having a through hole. The circuit board has a through hole. The core set penetrates the through hole of the first electrical conductor, the through hole of the circuit board, and the through holes of the plurality of spiral coils of the second electrical conductor, and covers at least one portion of the first electrical conductor and the second electrical conductor.

  • Patent number: 7982576
    Abstract: A transformer includes a first electrical conductor, a second electrical conductor and a core. The second electrical conductor is electromagnetically coupled with the first electrical conductor. The second electrical conductor includes at least one multilayer spiral coil, which is formed by winding a conductive wire and has a through hole at its central portion. Both ends of the conductive wire extend outward from a periphery of the multilayer spiral coil. The core penetrates through the through hole and covers at least one portion of the first electrical conductor and the second electrical conductor.

  • Publication number: 20080284551
    Abstract: Transformers are provided. A transformer comprises a ferromagnetic core unit; a bobbin coupled with the ferromagnetic core unit; at least a winding unit as a primary winding and at least a plate as a secondary winding. Also, some of the winding units can act as a secondary winding. At least a winding unit and at least a plate are alternatively stacked in a staggered manner. A conductive wire is wound around the winding unit.
