Thyristors

Thyristors are four-layer semiconductor devices, also known as a silicon controlled rectifier (SCR) It is like a fast static switch and is good for controlling large amounts of power, they can also control the speed of DC motors. You can learn more in our complete guide to thyristors.

How do thyristors work?
