  • Patent number: 11605489
    Abstract: An integrated magnetic element is provided, including a first magnetic-core frame, three second magnetic-core frames, and three coil windings. The first magnetic-core frame has a first side pillar and a second side pillar opposite to the first side pillar. The three second magnetic-core frames are arranged on the side corresponding to the first side pillar of the first magnetic-core frame, and are arranged in parallel with the axis of the first side pillar of the first magnetic-core frame. Each of the second magnetic-core frames has a first side pillar adjacent to the first side pillar of the first magnetic-core frame, and a second side pillar opposite to the first side pillar of itself. The three coil windings connect to a three-phase grid, and wind around the first side pillar of the first magnetic-core frame and the corresponding first side pillar of the second magnetic-core frame respectively.

  • Publication number: 20220130586
    Abstract: A magnetic element includes a first magnetic core, a second magnetic core, a first winding and a second winding. The first magnetic core includes a first lateral core part, a second lateral core part and a first middle core part between the first lateral core part and the second lateral core part. The second magnetic core includes a third lateral core part, a fourth lateral core part and a second middle core part between the third lateral core part and the fourth lateral core part. The third lateral core part is located beside the first middle core part. The second middle core part is located beside the second lateral core part. The first winding is wound around the first middle core part and the third lateral core part. The second winding is wound around the second middle core part and the second lateral core part.

  • Publication number: 20140313002
    Abstract: A non-linear inductor is disclosed herein. The non-linear inductor includes a first magnetic core, a second magnetic core, a third magnetic core, a fourth magnetic core, a fifth magnetic core and a coil unit. The first and the second magnetic core are disposed in parallel. The third magnetic core, the fourth magnetic core and the fifth magnetic core are all vertically disposed between the first and the second magnetic core. The fourth magnetic core is vertically disposed between the first and the second magnetic core. The fourth and the fifth magnetic core are disposed at both sides of the third magnetic core in parallel. The coil unit winds around the third magnetic core. A magnetic resistance of the fourth magnetic core passed through by an inductive magnetic flux is different from a magnetic resistance of the fifth magnetic core passed through by the inductive magnetic flux.
