Temperature controlled silicon controlled zero crossing switching circuit

Thyristor, the abbreviation of silicon-controlled rectifier element, is a high-power semiconductor device with a four-layer structure with three PN junctions, also called a thyristor. It has the characteristics of small size, relatively simple structure, and strong functions, and is one of the more commonly used semiconductor devices. This device is widely used in various electronic equipment and electronic products, and is often used for controllable rectification, inverter, frequency conversion, voltage regulation, contactless switch, etc. In household appliances, dimming lamps, speed-adjustable fans, air conditioners, televisions, refrigerators, washing machines, cameras, combination speakers, sound and light circuits, timing controllers, toy devices, radio remote controls, cameras and industrial controls are all widely used. silicon controlled device.
