摘要： A bobbin is designed to reduce the voltage stress between the winding layers of the inner winding of an inductive electronic component. A partition transversely extends from the winding surface of the bobbin to divide the winding surface into separated winding surface sections. A partition defines a passage for winding the coil from one winding surface section to the other winding surface section. Passage openings are positioned on each winding surface section relative the winding surface so that a portion of the partition is always between the passage opening and the oppositely disposed winding surface section.

摘要： A bobbin apparatus and associated magnetic component is configured to reduce gap losses associated with a core air gap in a bobbin-wound magnetic component such as an inductor or transformer. The bobbin includes a step structure protruding from the winding surface between bobbin ends. The step is operable to provide spacing between the conductive windings disposed on the bobbin and the core air gap inside the bobbin axial passage. The spacing reduces stray flux interactions with the conductive winding, thereby reducing gap losses and preventing undesirable heating of the winding and core. Additional winding configurations and methods for use with the bobbin apparatus are also provided.

摘要： A bobbin apparatus for a magnetic component includes a core passage having one or more core passage steps located therein. The core passage steps provide one or more gaps between a core disposed in the core passage and the bobbin body. A potting material may be disposed in the gap or gaps in some applications to enhance heat transfer and/or to improve magnetic component performance by reducing effects of fringing flux on inner windings. A method of assembling a magnetic component to include one or more gaps between the core and bobbin core passage is also provided.

摘要： A magnetic component for an electronic circuit includes a core having a core body and a core leg extending from the core body. The core body defines a core body height, and the core leg defines a core leg height less than the core body height. A conductive winding is positioned about the core leg. The winding defines a winding height. A winding height offset ratio is defined as the winding height divided by the core body height. In some embodiments the winding height offset ratio is less than about 1.1. The winding can be positioned on a bobbin structure disposed about the core leg. The magnetic component can be positioned in an enclosure to form an electronic device such as a power control or a power supply, and a thermally conductive gap-filler can be positioned between the magnetic component and the enclosure wall to dissipate heat from the magnetic component. The reduced height of the core leg provides a reduced gap distance between the core body and the enclosure wall for improving heat transfer, reducing thermal gap-filler material volume and reducing enclosure size. A method of forming an electronic device is also provided.
