It is the process by which an SCR or thyristor is brought to OFF state from ON state. We know that, an SCR is turned on by applying a gate signal to a forward biased SCR. Please read “ Required Conditions to Turn-on an SCR ” for better understanding.

Webb26 okt. 2016 · In DC circuits an SCR is not turned off by making the gate negative. You have to commute the load. This can be done by momentarily shorting anode to cathode or by opening the circuit with another device. Something is wrong if you can get a large reverse current through the gate because both the PN junctions it connects to will be … WebbTo disable scroll lock, press the Scroll Lock key (often labeled as ScrLk) on your keyboard.
