Silicon Controlled Rectifier (SCR) is a high-power electrical component, also known as thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power drive device to control high-power devices with low-power controls. It has been widely used in AC and DC motor speed control systems, power adjustment systems and servo systems.
