Problems solved by technology

Generally speaking, when current passes through a traditional inductor, only one kind of magnetic permeability will be generated, so the traditional inductor will be limited in use
[0004] In addition, because the resistance value will change with temperature, the inductor coils in the prior art are generally not suitable for current measurement, especially the inductor coils made of copper coils

Abstract

An inductor includes a first core, a second core, a protruding structure, at least two gaps and a conducting wire. The first core has a protruding portion. The second core is disposed opposite to the first core. The protruding structure protrudes from the protruding portion of the first core and toward the second core. The at least two gaps are between the protruding portion of the first core andthe second core. The conducting wire winds around at least one of the first and second cores. The conducting wire has a specific resistance value of 1.42 [mu][Omega]m or lower. When current passes through the conducting wires, magnetic flux changes in the at least two gaps to generate at least two inductance values with different descending changes .

Description

technical field [0001] The present invention relates to an inductor, in particular to an inductor having at least two inductance values ​​with different drop variations. Background technique [0002] An inductor is a passive electronic component that stores energy generated by a current passing through a magnetic field. The inductance value is used to measure the ability of an inductor to store magnetic energy. Inductors are generally wound into coils with wires, and according to Faraday's Law of Induction, the number of turns of wires can enhance the magnetic field in the coil. Inductance is created by the magnetic field formed around a current-carrying conductor, which has a tendency to resist changes in current. The number of turns of the wire, the cross-sectional area of ​​the wire, and the material of the wire all affect the inductance value. For example, using high permeability magnetic material (such as iron oxide compound) to wrap the conductor will increase the ma...
