Problems solved by technology

However, the space occupied by the common-mode inductor and differential-mode inductor of the circuit is not conducive to the miniaturization of electronic products, so it is necessary to propose an inductor device that can eliminate common-mode noise and differential-mode noise and has a smaller volume

Abstract

An inductance device with a common mode differential mode inductance function, comprising: an inductance frame body with a first winding portion, a second winding portion, and an accommodating area surrounded by the first winding portion and the second winding portion The first coil is wound on the first winding portion; the second coil is reversely wound on the second winding portion, and has a common mode inductance function; The part is joined to the inner edge of the inductor frame to be arranged in the accommodating area, and the magnetic conductive member is spaced between the first coil and the second coil so as to have magnetic induction with the first coil and the second coil respectively, and has a differential mode Inductance function, through the above structure, the inductance device of the present invention has the functions of common mode and differential mode inductors at the same time.

Description

technical field [0001] The invention relates to an inductor, in particular to an inductance device with the function of common-mode and differential-mode inductance. Background technique [0002] With the development of science and technology, electronic products are gradually developing in the direction of miniaturization, which increases the density of components in electronic products and is easily affected by electromagnetic interference (EMI). Generally, inductors are used to filter out EMI. In detail, the conducted EMI circulating in the circuit can be decomposed into two components of common mode noise and differential mode noise. In the prior art, common mode inductors (common mode choke, CMC) are used to eliminate common mode noise, and differential mode Differential mode choke (DMC) eliminates differential mode noise. However, the space occupied by the common-mode inductor and the differential-mode inductor of the circuit is not conducive to the miniaturization of...
