摘要： A magnetic element includes a first magnetic core, a second magnetic core and a plurality of conducting wires. The first magnetic core includes a first coiling body, a first protruding portion and a second protruding portion. The second magnetic core includes a second coiling body, a third protruding portion and a fourth protruding portion. A soldering surface of the first protruding portion is parallel and next to a soldering surface of the fourth soldering surface. Since an extension direction of the first magnetic core is extended from the soldering surface of the first protruding portion, an extension direction of the second magnetic core is extended from the soldering surface of the second protruding portion, and the plurality of conducting wires can be coiled on the first and the second coiling bodies respectively, the transformer can provide more space for coiling than the prior art.

摘要： A common mode filter includes an inner coil and an outer coil. The inner coil is formed of an inner wire and includes a plurality of inner turns. The outer coil is formed of an outer wire and includes a plurality of outer turns and at least one cross turn. A sum of the plurality of outer turns and the at least one cross turn is equal to a number of the plurality of inner turns, and the at least one cross turn comprises a N-th turn of the outer coil wound across a (N−1)th turn of the outer coil, and adjacent to two of the plurality of turns of the outer coil.

摘要： A composite magnetic component is provided. The composite magnetic component includes a magnetic flux-guiding unit, a first coil structure and a second coil structure. The first coil structure and the second coil structure are wound around a first winding portion and a second winding portion of the magnetic flux-guiding unit, respectively. A first magnetic flux results from the first coil structure and the magnetic flux-guiding unit. A second magnetic flux results from the second coil structure and the magnetic flux-guiding unit. The first magnetic flux is orthogonal to the second magnetic flux within the magnetic flux-guiding unit.

摘要： An apparatus of coupled inductors includes a first coil and a second coil arranged in a way that an inter-coil capacitance between the first coil and the second coil can keep electromotive forces induced by a first inductance of the first coil and a second inductance of the second coil about the same. As the current bypasses an unbalanced parasitic capacitor, a compensation capacitor disposed between the two coils can compensate the inter-coil capacitance of the parasitic capacitor. The apparatus of coupled inductors implemented with a specific coil arrangement or disposed with the compensation capacitor can keep the EMFs induced over the two inductances equal in amplitude, which prevents both the differential-mode and common-mode interference from being converted, improving the characteristics of mode conversion and is suitable to be utilized in a PoE system or the like.
