  • Patent number: 9251944
    Abstract: A variable coupled inductor includes a first core, two conducting wires, a second core and a magnetic structure. The first core includes two first protruding portions, a second protruding portion and two grooves, wherein the second protruding portion is located between the two first protruding portions and each of the grooves is located between one of the first protruding portions and the second protruding portion. Each of the conducting wires is disposed in one of the grooves. The second core is disposed on the first core. A first gap is formed between each of the first protruding portions and the second core and a second gap is formed between the second protruding portion and the second core. The magnetic structure is disposed between the second protruding portion and the second core and distributed symmetrically with respect to a centerline of the second protruding portion.

  • Patent number: 9230728
    Abstract: A magnetic device includes a T-shaped magnetic core, a wire coil and a magnetic body. The T-shaped magnetic core includes a base and a pillar, and is made of an annealed soft magnetic metal material, a core loss PCL (mW/cm3) of the T-shaped magnetic core satisfying: 0.64×f0.95×Bm2.20?PCL?7.26×f1.41×Bm1.08, where f (kHz) represents a frequency of a magnetic field applied to the T-shaped magnetic core, and Bm (kGauss) represents the operating magnetic flux density of the magnetic field at the frequency. The magnetic body fully covers the pillar, any part of the base that is located above the bottom surface of the base, and any part of the wire coil that is located directly above the top surface of the base.
