The structure of an inductor:
An inductor consists of a magnetic core and a coil. The magnetic core is the core part of the inductor, which determines the performance of the inductor. Commonly used magnetic core materials include ferrite, manganese-zinc ferrite, iron powder core, neodymium-iron-boron, and so on. The core is another important part of the inductor, which determines the capacity of the inductor. Commonly used wire materials include enameled wire, bare copper wire, and so on.
The working principle of inductors:
When current flows through a wire, a magnetic field is created around the wire. When the wire is wound into a coil, the magnetic field is concentrated inside the coil. If the core is enclosed in a core, the magnetic field will be even more concentrated.
According to the principle of electromagnetic induction, when a current is passed through a coil, an induced electromotive force is generated inside the coil. The direction of the induced electromotive force is opposite to the direction of the current. Therefore, the current flowing through an inductor is hindered by the induced electromotive force.
Inductance has a greater blocking effect on alternating current than direct current. This is because the direction of the alternating current will continue to change, and the induced electromotive force will also continue to change, thus creating a greater obstruction to the current.
The main characteristic parameters of inductors are:
1. Inductance: it is the main characteristic parameter of an inductor and indicates the ability of an inductor to store magnetic energy. The larger the inductance, the more magnetic energy the inductor can store.
2. Rated current: it is the maximum current that the inductor can withstand. Exceeding the rated current will cause damage to this inductor.
3. Loss: the inductor will produce losses during operation, mainly including copper losses and iron losses. Copper losses are due to the current flowing in the coil and iron losses are due to the magnetic core.
4. Frequency characteristics: the characteristics of an inductor are related to frequency. At low frequencies, the impedance of the inductor is large, and at high frequencies, the impedance of the inductor is small.
