  • Patent number: 8373532
    Abstract: In the winding wire at the winding completion end side, two wires are piled up vertically and wound together from the inner circumferential side towards the outer circumferential side. The winding wire at the winding start end side that has remained on the inner circumferential side is drawn forth from the inner circumferential side to the outer circumferential side so as to form a curve along the flat surface of the coil. In the crossing portions of the winding wire at the winding completion end side and the winding wire at the winding start end side, the two wires of each winding wire are superimposed and caused to cross each other in a state in which the wires are laid down transversely.

  • Patent number: 8350659
    Abstract: A transformer may include a first and a second continuous single piece multi-turn helical winding, one concentrically received by the other. The turns of the windings are electrically insulated from one another and spaced sufficiently close together to permit inductive coupling therebetween. The turns may be formed of a conductor having a rectangular cross-section, which may, or may not, include an electrically insulative sheath. The single piece multi-turn helical windings may have a continuous or smooth radius of curvature, with no discontinuities or singularities between first and second end terminals. The transformer may be formed by wrapping electrical conductor about a winding form. The transformer may be used in various electrical circuits, for example converter circuits.
