    摘要： Galvanically Isolated Single-Phase or Multi-Phase Power Converter for conversion between alternating current and direct current, comprising
    - DC terminals and AC terminals,
    - a parallel circuit comprising a DC link capacitor and at least two half-bridges, which is arranged between the DC terminals, the half-bridges each comprising two power semiconductors,
    - a control unit arranged to control the power semiconductors for interleaved power converter operation,
    - an inductor comprising a winding for each of the half-bridges, a first terminal of each of the windings being connected to a respective half-bridge and the second terminals of the windings being interconnected,
    - a further winding inductively coupled to the filter inductor and arranged between the AC terminals.

    摘要： A core component is made of a sintered body of an inorganic powder, in which the core component includes a columnar winding portion around which a conductive wire is wound, the columnar winding portion having a first axial end and a second axial end and a flange portion integrally formed with the winding portion at both axial ends of the winding portion, in which the columnar winding portion includes, in a cross section orthogonal to an axial center, a first region having a curved outer peripheral surface having a first radius of curvature and a second region having a curved surface having a second radius of curvature, the second radius of curvature is smaller than the first radius of curvature and the first region and the second region are connected with each other via a first projection.

    摘要： A coil component (100) includes: a core having first and second shafts (11, 12) arranged in a line, and first and second opposed members (15, 25); a case (30) supporting the core and having a housing (36) accommodating the core, and first and second outer walls (40, 50) opposing each other; a coil (60) wound around the first and second shafts (11, 12); and first and second metal terminals (70) being electrically connected to the coil (60) and being provided at the first and second outer walls (40, 50), respectively. The first and second opposed members (15, 25) are opposed to each other and sandwich the first and second shafts (11, 12) therebetween.
