The winding angles of the first busbar and the second busbar are respectively kept consistent, so that the uniform distribution of an electric field is ensured, a good filtering effect is generated, the electromagnetic interference is reduced better, and the electromagnetic compatibility of the system is improved.
Furthermore, the first busbar and the second busbar are wound on the middle shaft, and the wiring of the first busbar and the wiring of the second busbar are kept parallel. The first busbar and the second busbar are arranged in parallel, the manufacturing and installation difficulty is reduced, the system stability is enhanced, the first busbar and the second busbar can be connected in an external mode during processing, and the first busbar and the second busbar can be kept parallel all the time conveniently.
Further, the central shaft is made of ferrite material. The middle shaft of the ferrite material can increase the inductance generated by the spiral first busbar and the spiral second busbar, and under the same condition, the number of winding turns of the first busbar and the second busbar can be reduced, and the occupation of the assembly on space is reduced. The ferrite material may also be replaced by other materials having a high magnetic permeability.
Furthermore, the first busbar and the second busbar are fixed on the middle shaft through an insulating adhesive. The position and the angle of the first busbar and the second busbar on the middle shaft are kept stable, the first busbar and the second busbar are prevented from falling off from the middle shaft, the stability of the generated inductance value is ensured, and the effect of continuously reducing electromagnetic interference is achieved.
