SCR thyristor is a semiconductor device used to control current. The full name of SCR is silicon controlled rectifier, also known as thyristor.
Like diodes, SCRs only allow current to flow in one direction. It rectifies alternating current (AC) to direct current (DC) when triggered.
Unlike a diode, an SCR can be turned on and off by applying a small current to its gate terminal. This makes it a controllable switch.
Some common uses include:
Power control, voltage regulation, rectification, inrush current limiting, motor control, lighting, HVDC transmission, induction power supplies.
The SCR thyristor is a versatile semiconductor device used in a variety of applications requiring precise control of high-power electrical loads. Their ability to handle high currents and voltages while being controlled makes them valuable components in electronics and electrica
