  • Patent number: 10594206
    Abstract: The invention comprises an inverter/converter yielding high frequency harmonics and/or non-sixty Hertz output coupled to a high frequency inductor-capacitor filter apparatus. For example, an inverter/converter apparatus is provided that uses a silicon carbide transistor to output power having a carrier frequency modulated by a fundamental frequency and a set of harmonic frequencies, where the minimum carrier frequency is above that usable by an iron-steel inductor, such as greater than ten kiloHertz at fifty or more amperes. An inductor-capacitor filter, comprising an inductor having a distributed gap core material, receives power output from the inverter/converter and processes the power by passing the fundamental frequency while reducing amplitude of the harmonic frequencies.

  • Patent number: 10424430
    Abstract: A module includes an insulating layer, a ring-shaped magnetic core built in the insulating layer, a coil electrode disposed in the insulating layer so as to spirally wind around the magnetic core, and heat-dissipating metal bodies respectively disposed outside and inside the magnetic core within the insulating layer. Building the magnetic core into the insulating layer as described above eliminates the need to provide the principal face of the insulating layer with a large mounting area for mounting a coil formed by the magnetic core and the coil electrode. This allows the area of the principal face of the insulating layer to be reduced to achieve miniaturization of the module. The presence of the heat-dissipating metal bodies respectively disposed outside and inside the magnetic core within the insulating layer improves dissipation of the heat generated from the coil.

  • Patent number: 10403431
    Abstract: A coil component that includes a coil having a thick coil core and good inductance characteristics and is able to narrow the pitch of a coil electrode is provided. The wiring of a coil electrode in a direction across the direction of a winding axis of the coil electrode includes a plurality of first metal pins and a plurality of second metal pins. By elongating each metal pin, the wiring of the coil electrode is easily elongated in a metal pin direction. Thus, a coil core is easily thickened in the metal pin direction. The wiring of the coil electrode can be formed in the metal pin direction only by arranging the metal pins. Thus, it is possible to provide a coil component that includes a coil having the thick coil core and good inductance characteristics and is able to narrow the pitch of the coil electrode.

  • Patent number: 10249716
    Abstract: A combination switch includes an Insulated Gate Bipolar Transistor (IGBT), an anti-parallel diode, and a saturable inductor. The diode and inductor are coupled in series between a collector and an emitter of the IGBT. The inductor is fashioned so that it will come out of saturation when a forward bias current flow through the diode falls below a saturation current level. When the diode current falls (for example, due to another combination switch of a phase leg turning on), the diode current initially falls at a high rate until the inductor current drops to the saturation current level. Thereafter, the diode current falls at a lower rate. The lower rate allows the diode current to have a soft landing to zero current, thereby eliminating or reducing voltage and/or current spikes that would otherwise occur. Multiple methods of implementing and manufacturing the saturable inductor are disclosed.

    Abstract: Two conducting wires are used in one embodiment of an inductor. Opposite ends of each of the conducting wires are connected to leader lines (terminals) shared by the conducting wires. Each of the conducting wires is wound to make half a round of an annular or ring-like magnetic substance. One of the conducting wires is wound around a lower half area of the magnetic substance to form one winding while the other conducting wire is wound around an upper half area of the magnetic substance to form another winding. In this manner, the distance between the leader lines can be increased to eliminate parasitic capacitance between the leader lines. The magnetic fluxes generated by current flowing in the two windings are in the same direction. Thus, it is possible to provide an inductor whose total parasitic capacitance is reduced. In other embodiments, additional conducting wires are used.

  • Patent number: 8299879
    Abstract: A transformer assembly (300) for use with an internal load (307) includes a transformer core (323) having a primary winding (405). A first electrode (303) and second electrode (319) are used for contacting an internal load (307). A secondary circuit is formed that includes the first electrode (303), the second electrode (319) and conductors (301,313, 317) positioned between the first electrode (303) and second electrode (319). The transformer assembly (300) is arranged so that the conductors (301, 313, 317) surround the primary winding (405), transformer core (323), the first electrode (301) and second electrode (319). The transformer assembly (300) may be used in an electrode furnace or other high current and voltage applications requiring high efficiency in a small package.

  • Patent number: 8209850
    Abstract: In a method for manufacturing pencil cores a continuous strip of electrical steel is provided. The continuous strip is cut to create a plurality of starting strips as laminations each having a length longer than a desired length of the pencil cores and at least one of the strips having a strip width at least equal to or larger than a desired diameter of a cross-section of the pencil cores. The starting strips are provided with a bonding layer. The starting strips are stacked and then heated and cured to create a bonded stack. The bonded stack is machined to a substantially circular cross-section. Without a de-burring or de-smearing operation after the machining, the machined bonded stack is cut to create a plurality of pencil cores of the desired length. The pencil cores created by the method are substantially round, and have no welds at end faces.

  • Patent number: 8193895
    Abstract: A magnetic assembly includes a magnetic core, a circuit board and multiple conductive elements. The circuit board includes multiple conductive regions. The conductive elements stride over the magnetic core. Each of the conductive elements includes a first terminal, a second terminal and a connecting part. The connecting part is arranged between the first terminal and the second terminal for connecting the first terminal with the second terminal. The first terminal and the second terminal of each conductive element are respectively connected to two adjacent conductive regions. The multiple conductive elements and the multiple conductive regions collectively define multiple loops. The multiple loops interact with the magnetic core to generate inductance.

  • Patent number: 8191240
    Abstract: A method for winding a lead wire on a multi-winding electronic component is provided. The method can prevent winding slack of the lead wire, a break of the lead wire, and/or a terminal disconnection failure. A lead wire is wound around a winding core by a certain number of turns to form at least one first layer. Next, the lead wire is folded back toward an electrode, is pulled toward the electrode at an end-of-winding side so as to be across the second layer. Then, the lead wire is caught at a bottom part of the collar to form a final terminal part for boding to the electrode.
