摘要： A magnetic assembly includes a single bobbin structure that supports a first coil and a second coil. A first E-core has a center leg positioned within the first coil. A second E-core has a center leg positioned within the second coil. An I-core is positioned between the first E-core and the second E-core. The I-core completes a first set of magnetic paths between the center leg and outer legs of the first E-core and also completes a second set of magnetic paths between the center leg and outer legs of the second E-core. The two E-cores and the I-core are stacked in a vertical E-I-E configuration with respect to a common set of pin rails. In one embodiment, the first coil and the first E-core are configured as a transformer; and the second coil and the second E-core are configured as an inductor.

摘要： A magnetic assembly includes a bobbin with two end flanges. A passageway extends longitudinally between the end flanges. An inner core extends through, and is centered in, the passageway. The inner core has first and second end surfaces, each surface proximate to one of the end flanges. A rectangular outer core is positioned around the bobbin with inner surfaces of the outer core close to the outer surfaces of the end flanges of the bobbin. A respective gap is formed between each end of the inner core and the adjacent inner surface of the outer core. The passageway includes crushable ribs that secure the inner core within the passageway. The outer surfaces of the end flanges include crushable ribs that secure the core with respect to the bobbin. The passageway and inner core may have an oval-shaped profile. The passageway and inner core may have a circular profile.

摘要： An edge mount magnetic component includes a bobbin and two E-core halves. The bobbin is configured to receive the two E-core halves when body portions of the two E-core halves are positioned vertically. The bobbin includes a first outer flange, a second outer flange, and a passageway spanning therebetween. The bobbin further includes first, second, third, and fourth pin supports. The first and second pin supports are connected to an outer surface of the first end flange and are spaced apart by at least a width of the passageway. The third and fourth pin supports are connected to an outer surface of the second end flange and are spaced apart by at least the width of the passageway. The bobbin further includes slots for routing a winding to a pin and includes walls to ensure the winding is electrically separated from the E-core halves.

摘要： A magnetic component has a variable inductance over a range of DC bias currents. The component includes a bobbin with a coil positioned around a passageway between first and second end flanges. First and second E-cores have respective middle legs positioned in the passageway with end surfaces of the middle legs juxtaposed within the passageway and spaced apart by a first magnetic gap. An I-bar is positioned in the passageway parallel to and spaced apart from respective first longitudinal surfaces of the middle legs to form a second magnetic gap between the I-bar and the longitudinal surface of the middle leg of the first E-core and to form a third magnetic gap between the I-bar and the longitudinal surface of the middle leg of the second E-core. The magnetic component provides higher inductances for lower bias currents and provides lower inductances for higher bias currents.

摘要： A magnetic assembly includes a bobbin and first and second cores. Each core has a main body. At least one of the cores has first and second outer legs and a center leg extending from the main body. The bobbin includes a first channel on a first end flange and a second channel on a second end flange. Each channel includes a plurality of crushable ribs that extend into the channel. The first and second cores are inserted into the respective first and second channels to engage and crush the crushable ribs. The crushed ribs frictionally engage the main bodies of the two cores to retain the two cores in a fixed relationship with the bobbin without requiring tape or glue. In one embodiment, both cores are E-cores. In another embodiment, one core is an extended E-core and the other core is an I-core.

摘要： A magnetic component apparatus includes a bobbin having a bobbin body, a first pin rail, a second pin rail, and a longitudinal axis. First and second pin rows are located on the first pin rail. The second pin row is located at an exterior position from the first pin row. A third pin row is located on the second pin rail. The first, second, and third pin rows can be oriented in a direction transverse to the longitudinal axis. A plurality of windings can be located on the bobbin body. Some embodiments can include a fourth pin row located on the second pin rail, the fourth pin row located at an exterior position from the third pin row. In some embodiments one or more wire guide channels can be defined in the first or second pin rails to help keep breakout wires from the plurality of windings separate.

摘要： A magnetic assembly structure includes a bobbin, an outer core, an inner core, and a gap spacer. The bobbin has first and second flanges. The bobbin has a passageway extending between the first and second flanges. The passageway has at least one crushable passageway rib and a channel wall parallel to the second flange. The outer core is positioned around the first and second flanges. The outer core includes an opening positioned near the first flange. The inner core is positioned in the opening and in the passageway. The gap spacer is positioned between the inner core and an inner surface of the outer core. The gap spacer and outer core are held in frictional engagement between the inner core and channel wall. The gap spacer defines a gap distance which is adjustable by replacing the gap spacer with one of having a different thickness. Adjusting the gap distance modifies the inductance.

摘要： A tunable magnetic assembly includes a bobbin, an outer core, and an inner core. The bobbin has a first and second flanges. The bobbin has a passageway extending between the first and second flange. The passageway has a spiral track defined in a passageway surface. The outer core is positioned around the first and second flanges. The outer core includes an opening positioned near the first flange. The inner core is positioned in the opening and in the cylindrical passageway. The inner core includes at least one protrusion extending from an outer surface and configured to engage the spiral track. A gap distance is defined between the inner core and a portion of the outer core near the second flange. The gap distance is adjustable by moving the protrusion within the spiral track. Adjusting the gap distance modifies the inductance.
