A transformer is a static electromagnetic device that converts electrical energy from one value to another. Basically, the transformer consists of an iron core and two coils called primary and secondary windings.
Transformer is a device that transforms AC voltage, current and impedance. When AC current is connected in the primary coil, AC magnetic flux will be generated in the iron core (or magnetic core), causing voltage (or current) to be induced in the secondary coil. The transformer is composed of an iron core (or magnetic core) and a coil. The coil has two or more windings, of which the winding connected to the power supply is called the primary coil, and the other windings are called the secondary coil.
The changing current in one coil of the transformer produces a changing magnetic flux, and then induces a changing electromotive force on the second coil wound on the same iron core. Electric energy can be transmitted between two coils, and there is no metal connection between the two circuits. The transformer can increase or decrease voltage and current levels without changing the frequency.
However, the winding process of transformer will have different requirements according to different applications (different purposes). The main functions of the transformer are: voltage transformation; Impedance transformation; Isolation; Voltage stabilization (magnetic saturation transformer), etc. the commonly used iron core shapes of transformers generally include E-type and C-type iron cores.
Transformers can be divided into: distribution transformer, power transformer, fully sealed transformer, combined transformer, dry-type transformer, single-phase transformer, electric furnace transformer, rectifier transformer, reactor, transformer, anti transformer, lightning transformer, box transformer, box transformer.
The most basic type of transformer consists of two groups of coils wound with wires, which are inductively combined with each other. When an AC current (with a certain known frequency) flows through one group of coils, an AC voltage with the same frequency will be induced in the other group of coils, and the magnitude of the induced voltage depends on the coupling of the two coils and the degree of magnetic cross-linking.
