Abstract: The present disclosure discloses a planar magnetic element and a manufacturing method thereof. The planar magnetic element includes: a housing, with an internal space; a core, accommodated in the internal space of the housing, and the core including at least one limb; at least one planar winding corresponding to the limb; and potting adhesive, filled in all air gaps in the internal space of the magnetic element, and blocking the clearance and creepage path between the planar winding and the core and/or between the two planar windings. The present disclosure may significantly reduce the volume of the magnetic element and greatly increase the partial discharge extinction voltage, thereby reducing the partial discharge risk of the magnetic element and improving the reliability. Moreover, the compact structure of the planar magnetic element is conducive to improving the power density of the module.

Abstract: A reactor (2) includes a bobbin (10). The bobbin is a resin-made bobbin, and has a pair of flanges (12a, 12b) that face each other. Coils (3) are wound around the bobbin between the pair of flanges. Each of a pair of plates (20) is bridged from the flange on one side, which is one of the pair of flanges, to the flange on the other side, which is one of the pair of flanges. The pair of plates abuts on circumferences of the coils between the pair of flanges. A resin cover (40) covers one of two outer peripheries of the coils. The two outer peripheries are defined by the pair of plates.

Abstract: Provided are a core and coil molding structure and a manufacturing method thereof which are capable of eliminating a void between coil layers to prevent foreign materials from entering therein, and which improve the vibration resistance and shock resistance of a reactor. A core and coil molding structure includes a coil that is a rectangular coil, a core yoke member in a block shape, and a resin member molding at least a part of those. The presence of a positioning member in a pin shape which positions the coil within a mold forms a groove in the inner circumference of the coil in the resin member.
