  • Patent number: 11800633
    Abstract: An inductor and a power module are respectively provided. The inductor includes an insulating body and a conductive body. The insulating body has a top surface and a bottom surface. The conductive body includes two pin parts and a heat dissipation part. A portion of each of the pin parts is exposed outside the bottom surface. The portions of the two pin parts exposed outside the insulating body are configured to fix to a circuit board. The heat dissipation part is connected to the two pin parts, the heat dissipation part is exposed outside the top surface, and the heat dissipation part is configured to connect to an external heat dissipation member. When the inductor is fixed to the circuit board through the two pin parts exposed outside the bottom surface, the two pin parts and the bottom surface jointly define an accommodating space for accommodating a chip.

  • Publication number: 20200058435
    Abstract: An inductor structure with height limit, which comprises: a conductor formed in a bent shape, and is set with a plurality of bending-portions, wherein a first connecting-pin and a second connecting-pin are respectively set at two ends of the conductor; a first magnetic core set with a first combining-surface, wherein the first combining-surface forms a concave groove to accommodate the conductor; and a second magnetic core set with a second combining-surface, wherein the second combining-surface forms a second concave groove to accommodate the conductor; wherein the second combining-surface is combined on the first combining-surface; wherein the conductor is sheathed and set between the first magnetic core and the second magnetic core, and is set with the first connecting-pin and the second connecting-pin exposedly. Therefore, the present invention can increase the magnetic (coupling) route length under the height limit to produce an effect of increasing the inductance value and current.

  • Patent number: 10522281
    Abstract: The large-current inductor includes a first core member having a first winding piece, a second winding piece, a first indentation, and a second indentation; a second core member having a third winding piece, a fourth winding piece, a third indentation, and a fourth indentation; a third core member attached and joined to first lateral sides of the first and second core members; and a fourth core member attached and joined to second lateral sides of the first and second core members. A first coil member winds around the first and third winding pieces, and has its ends embedded into the first and third indentations. A second coil member winds around the second and fourth winding pieces, and has its ends embedded into the second and fourth indentations. The inductor enhances efficiency of energy storage by mutual inductance, and limits large current flow by leakage inductance.

  • Publication number: 20180301276
    Abstract: The multiple winding inductor assembly includes a first core piece, a second core piece, a first conductor, and a first core assembly. The first core assembly includes a third core piece and a second conductor. The first and second conductors, together with the first, second, and third core pieces, form multiple inductors that, when working individually, do not cause mutual inductance on those not at work, thereby avoiding energy consumption. In addition, the inductor assembly may be extended in only one direction when cascading more inductors, facilitating circuit design and layout, and the configuration of the inductor assembly on the circuit board.
