Description

Inductance structure capable of simultaneously increasing inductance value and current

This creation is an inductive structure, especially an inductive structure that can increase both inductance and current.

According to the general inductance structure, as disclosed in Patent No. M429976 of the Republic of China, please refer to the first figure, which mainly includes an accommodating space in the first magnetic core and a second magnetic core in the accommodating space. The second magnetic core is surrounded by a coil, so as to generate a magnetic field through the coil through the current, so that the inductor can achieve the effect of storing and releasing energy.

Although the general inductance can generate electromagnetic induction by current through the coil, when the volume requirement of modern circuits is getting smaller and smaller, it is often impossible to effectively reduce the number of coils of the wound inductor, but traditional improvements will still be encountered The negative DC current (IDC) is insufficient or the series inductance value (Ls) is attenuated too much.

Therefore, how to eliminate the above deficiencies is the technical difficulty for the creator of this case.

In view of the above problems of the existing inductance structure, the purpose of this creation is to provide an inductance structure that can simultaneously increase the inductance and current.

In order to achieve the above purpose, this creative department provides a way to simultaneously increase the sense value and electricity Inductive structure of flow, which contains:

An alloy core. The alloy core is provided with a coil accommodating groove and a surface. The coil accommodating groove is provided with at least one pin accommodating groove. The alloy core is H-shaped;

A coil, which is provided in the coil accommodating groove of the alloy core, the coil is a single coil, at least one bent portion is provided on the coil, and each bent portion is extended with a pin, each of which is connected The feet are respectively arranged in the pin accommodating slots of the coil accommodating slot;

A manganese zinc ferrite core, the manganese zinc ferrite core is provided on the surface of the alloy core, and the manganese zinc ferrite core is in a shape of a line.

Therefore, by setting the manganese-zinc-ferrite core on the surface of the alloy core, the series inductance value and the maximum DC current value can reach the required value, which can simultaneously achieve the enhancement of the sense value and Current value.
