What is Thyristor and How it Works?

Thyristor, commonly known as SCR, its standard term is reverse blocking three terminal thyristor. Thyristors are high-power semiconductor devices with switching and rectifying functions, and are used in various circuits, such as controllable rectifying and converting, inverter and contactless switch. As long as it provides D and weak trigger signals, it can control the strong current output. Therefore, it is a bridge for semiconductor devices to enter the strong field from the weak field.
