Embodiment

[0009] see figure 1 As shown, a transformer for improving EMI includes a winding frame 1, a primary winding group 2, a secondary winding group 3, and an auxiliary winding group 4; the primary winding group 2 surrounds the winding frame 1 and coupled to the input circuit 5; the secondary winding group 2 is wound on the bobbin 1 and coupled to the output circuit 6; the auxiliary winding group 4 is wound on the bobbin 1 And sandwiched in the secondary winding group 3 , and coupled to the input circuit 5 .

[0010] In the transformer of the present invention, the auxiliary winding group is placed between the secondary winding groups, which can form a better bridge capacitance effect between the primary winding group and the secondary winding group, so as to improve EMI.

Abstract

The invention discloses an EMI-ameliorated transformer, comprising a winding frame, primary windings, secondary windings and an auxiliary winding, wherein the primary windings are wound on the winding frame and coupled to an input circuit, the secondary windings are wound on the winding frame and coupled to an output circuit, and the auxiliary winding is wound on the winding frame, is sandwiched between the secondary windings and is coupled to the input circuit. The EMI-ameliorated transformer has the beneficial effect that the auxiliary winding is arranged between the secondary windings so that a good flying capacitor effect can be formed between the primary windings and the secondary windings and thus EMI is ameliorated.

Description

technical field [0001] The invention relates to a transformer for improving EMI, belonging to the technical field of transformers. Background technique [0002] Magnetic components such as transformers and inductors are very important in switching power systems. The production of this kind of magnetic components can directly wind the insulated wires on the magnetic core, such as single-layer insulated wires or three-layer insulated wires, or first wind the insulated wires into a cake shape or set the insulated wires on the winding wire On the winding area of ​​the frame, and then assemble with the magnetic core. The switching power supply system uses switching components to generate electromagnetic interference (EMI). Electromagnetic interference can interfere through conduction and radiation, and even damage other electronic components or electronic equipment. Contents of the invention [0003] Aiming at the above disadvantages, the present invention provides a transf...
