An AC voltage output from the secondary winding unit is transmitted to and rectified by the rectifying circuit board. Therefore, the size of the transformer is compact, and heat energy generated by electronic elements mounted on the rectifying circuit board is effectively dissipated to maintain normal operation of the transformer. Further, since the transmission path from the secondary winding unit to the rectifying circuit board is short, energy loss is reasonably reduced when the transformer is operated under a high frequency situation or a larger current mode.

The windings may be primary and secondary windings of a transformer, wherein all or part of a magnetic core thereof is embedded in a component layer of the wafer level package. If the core includes a part bonded to a surface of the package, that part of the core may be E-shaped with legs extending into the routing layers, and, in some cases, through the routing layers. Routing layers may be formed on both sides of the component layer to accommodate the transformer windings, in some instances.

  • Patent number: 8754739
    Abstract: A reactor having a good heat dissipation effect is provided. The reactor includes one coil formed by winding a wire, a magnetic core arranged inside and outside the coil and forming a closed magnetic circuit, and a case for housing an assembly of the coil and the magnetic core. An end surface of the coil has a race track shape, and the coil is housed in the case such that the axial direction of the coil is parallel to an outer bottom surface of the case. A part of an outer peripheral surface of the coil is covered with the magnetic core (outer core portion), and a remaining part thereof not covered with the magnetic core is contacted with an inner bottom surface of the case. Since a part (mainly a linear portion) of the outer peripheral surface of the coil is directly contacted with the inner bottom surface of the case, heat of the coil can be directly dissipated such that the heat is released through the case to an installation target, e.g., a water cooling base, on which the case is installed.

  • Patent number: 8736413
    Abstract: In a laminated inductor element, a magnetic ferrite layer sandwiched between two conductor patterns is thinner than other magnetic ferrite layers. Therefore, a crack occurs in the magnetic ferrite layer due to firing. As a result of the occurrence of this crack, a stress applied to each layer is relaxed, and it becomes possible to avoid warpage, a crack, or the like. In addition, in the laminated type inductor element, the two conductor patterns are electrically connected by two via holes, and subjected to a same potential. Since the two conductor patterns correspond to a same wiring pattern and a coil of coil conductor is defined by the two conductor patterns, even if upper and lower coil conductors are electrically in contact with each other due to the crack, the two conductor patterns are not put into a short-circuited state.

  • Patent number: 8723631
    Abstract: A printed circuit board includes metallization layers are stacked along a vertical direction and separated mechanically from one another by electrically insulating layers. A coil extends along a vertical winding axis and has turns formed by conductive tracks made in respective metallization layers, the turns being electrically connected to one another by pads going through at least one of the electrically insulating layers. A superimposition, in a plane parallel to the metallization layers, of the conductive tracks of the coil, made in a first metallization layer and a second metallization layer, that are immediately consecutive in the vertical direction, forms a pattern having two axial symmetries relative to X and Y axes orthogonal to each other and parallel to the metallization layers. The conductive tracks of each of the superimposed metallization layers are devoid, of themselves, of axial symmetry relative to the X or Y axes.
