摘要： According to various embodiments, a power converter circuit is disclosed. The power converter circuit includes at least two vertically stacked printed circuit boards (PCBs) comprising a top PCB and a bottom PCB. The power converter circuit further includes at least one multiphase coupled inductor placed between the top PCB and the bottom PCB. The top PCB is coupled to the bottom PCB via at least one conductive winding of the multiphase coupled inductor. The power converter circuit further includes at least one circuit module placed above the top PCB and at least one power source placed below the bottom PCB. The multiphase coupled inductor is configured to deliver current vertically from the bottom PCB to the top PCB.

摘要： The present disclosure discloses a dry-type transformer with an elliptical iron core, comprising a transformer housing, a heat dissipation mechanism, an elliptical iron core, a coil, a clamping mechanism and an upper cover, the heat dissipation mechanism being arranged in a horizontal direction and fixedly assembled with the transformer housing, one end, away from the transformer housing, of the heat dissipation mechanism being in contact with ground, the elliptical iron core being arranged in a vertical direction inside the transformer housing, the coil being wound on the elliptical iron core, the clamping mechanism being sheathed on one side, away from the elliptical iron core, of the coil, the upper cover being arranged at a top end of the transformer housing, and the upper cover being fixedly assembled with the transformer housing via a bolt structure. The present disclosure uses an iron core with an elliptical cross section, wherein three-phase iron cores are arranged in a regular triangle shape and are respectively located at each midpoint position of edges of the triangle, and a winding manner of coil adjacent to the iron core is also different. In addition, a clamping mechanism is provided in the present disclosure, so that it is possible to implement a remedy for re-detachment of the coil during clamping, thereby extending a service life of the dry-type transformer.

摘要： The disclosure concerns a magnetic component and a power converter including the same. The magnetic component includes at least one magnetic core, where at least one gap is formed between end surfaces, especially opposing end surfaces, of the magnetic core(s). The magnetic component further includes at least one electrical winding surrounding at least a part of the at least one magnetic core, and a shielding device for shielding fringing fields of the at least one gap. The shielding device includes: a holding unit attached to the at least one magnetic core and/or to the at least one electrical winding in a periphery of the at least one gap; and at least one shield member attached to the holding unit. The at least one shield member is configured to shield gap fringing fields in the periphery of the gap.

摘要： A coil support for an electric motor includes a coil holding arrangement having coil holding portions configured to hold a corresponding number of coils. A connectics receiving arrangement is configured as a housing for interconnected cables and coil wires. The connectics receiving arrangement comprises a cable receiving portion having recesses configured to receive the cables and a wire receiving portion having through-holes extending from a top surface to a bottom surface of the wire receiving portion. The top surface of the wire receiving portion is arranged adjacent the coil holding arrangement and the bottom surface of the wire receiving portion is located in the connectics receiving arrangement so as to provide for electrical interconnection of the coils with corresponding ones of the cables. A separation wall is arranged between the bottom surface of the wire receiving portion and the coil holding arrangement.

摘要： A coil module comprises a carrier which has a polygonal basic shape with four to twelve corners and comprises a magnetic material. A coil is arranged on the carrier. The polygonal basic shape is rotationally symmetrical with an angle of 360°·2 divided by the number of corners. To produce a coil assembly, a plurality of coil modules can be connected to each other. This makes it possible to produce an efficient coil assembly for wireless electromagnetic energy transmission in a simple and flexible manner.

摘要： Terminal electrodes are disposed on mounting surfaces of flanges of a substantially drum-shaped core that are directed to a mounting substrate. A rounded surface is formed on the mounting surface. An end portion of the wire extends along the rounded surface from a side on which the inner end surface is present toward a side on which the outer end surface is present.

摘要： A power-transmission-side coil unit includes: a housing including a metal case body and a resin cover, an electric device provided in the housing, a metal substrate disposed between the cover and the electric device and covering the electric device, and a power transmission coil. The case body includes a base portion, and a ring-shaped wall portion protruding toward the cover along the outer peripheral edge of base portion inside the outer peripheral edge of base portion. The metal substrate includes a partition wall disposed between the cover and the electric device, and a peripheral wall extending from the partition wall toward the base portion. An end portion of the peripheral wall is disposed in the D direction relative to the upper face of the ring-shaped wall portion. At least part of a lateral face of the peripheral wall is in contact with a lateral face of the ring-shaped wall portion.
