What is thyristor? what is it used for ?

SCR is the abbreviation of SCR rectifier element. It is a high-power semiconductor device with a four-layer structure with three PN junctions, also known as a ٿائرائزر. It has the characteristics of small size, relatively simple structure, and strong functions. It is one of the more commonly used semiconductor devices. The device is widely used in various electronic equipment and electronic products, and is mostly used for controllable rectification, inverter, frequency conversion, voltage regulation, non-contact switch, etc. In household appliances, dimming lights, speed-regulating fans, air conditioners, televisions, refrigerators, washing machines, cameras, audio systems, sound and light circuits, timing controllers, toy devices, radio remote controls, cameras and industrial controls are all widely used The thyristor.
