Abstract

An inductance device comprises a first coil, a second coil, at least one first connecting piece, at least one second connecting piece and a first center tap end. The first coil comprises a plurality of primary coils. The second coil comprises a plurality of secondary coils. The plurality of primary coils and the plurality of secondary coils are arranged in an interactive manner. At least one first connecting piece is coupled with the primary coil arranged on the outer side and the primary coil arranged on the inner side in the plurality of primary coils. At least one second connecting piece is coupled with the secondary coil arranged on the outer side and the secondary coil arranged on the inner side in the plurality of secondary coils. The first center tap end is coupled to a first primary coil disposed on an outer side of the plurality of first primary coils.

Description

technical field [0001] The present disclosure relates to an electronic device, and more particularly to an inductive device. Background technique [0002] Various existing inductors have their advantages and disadvantages. For example, a spiral inductor has a high Q value and a large mutual inductance. For the twin inductor, it is difficult to design it as a symmetrical structure, and the application frequency band of the twin inductor is relatively narrow. Therefore, the application ranges of the above-mentioned inductors are limited. Contents of the invention [0003] To solve the above problems, a technical embodiment of the present disclosure relates to an inductance device, which includes a first coil, a second coil, at least one first connecting element, at least one second connecting element, and a first central tap end. The first coil includes a plurality of first coils. The second coil includes a plurality of second coils. The first coil is arranged alternatel...
