  • Publication number: 20170103843
    Abstract: Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference. An iron core material (14) with large magnetic permeability out of iron core materials with different magnetic permeabilities is arranged on the inner circumference side. Further, when the iron core materials with different magnetic permeabilities are alternately arranged, the iron core materials (11) with the same magnetic permeability are configured to gradually change in thickness to ease an excessive magnetic flux density distribution in the iron core.

  • Patent number: 6075431
    Abstract: A transformer has a bobbin made of a resin material having flanges (2a to 2f) formed thereon, at least three chambers defined between the adjacent flanges. A primary auxiliary winding (P2), which supplies an electric power to an drive-control and overvoltage protection circuit and a primary excitation winding (P1-1) are wound on the chambers (3a and 3c) with at least one chamber (3b) disposed therebetween. A secondary winding (S2) which consumes the electric power always is wound on the chamber (3b) between the chambers (3c and 3a) on which the primary excitation winding (P1-1) and the primary auxiliary winding (P2) are wound.

  • Patent number: 6002319
    Abstract: An inductance device comprises: an EE type ferrite core with an air gap at a center leg portion; a bobbin having at least three chambers wound by coils, said ferrite core being placed on said bobbin; and a shield coil formed by a first part and a second part of the coil, in which the first part is wound a chamber surrounding a peripheral portion of the air gap and the second part is wound the chamber in a reverse direction of the first part, the ends of the shield coil being short-circuited. In the inductance device with gap, the first and second parts of the coil are wound in the chamber surrounding the peripheral portion of the air gap in opposite direction each other, and the ends of the coil are shorted circuited. Thus, it is formed the shield coil for a leak magnetic flux from the air gap containing a component perpendicular to the main magnetic flux.
