what is the use of thyristor
- the thyristor or silicon controlled rectifier, SCR is a device that is widely used for controlling or switching power and often high voltage AC or DC circuits.In this section.he silicon controlled rectifier, SCR or thyristor symbol used for circuit diagrams or circuit seeks to emphasis its rectifier characteristics while also showing the control gate. As a result the thyristor symbol shows the traditional diode symbol with a control gate entering near the junction.
