The working principle of thyristor

Thyristor is the abbreviation of thyristor rectifier element. It is a high-power semiconductor device with a four-layer structure with three PN junctions. It is generally formed by reverse connection of two thyristors. Its function is not only to rectify, but also to use It is used as a non-contact switch to quickly turn on or off the circuit, realize the inversion of the direct current into the alternating current, the alternating current of one frequency into the alternating current of another frequency, and so on. The thyristor, like other semiconductor devices, has the advantages of small size, high efficiency, good stability, and reliable operation. With its emergence, semiconductor technology has moved from the weak current field to the strong current field, and has become a component used in industries, agriculture, transportation, military scientific research, as well as commercial and civilian electrical appliances.
