In an SCR circuit, the angle of conduction can be changed by__________________?
Correct answer: B. Changing gate voltage
- A. Changing anode voltage
- B. Changing gate voltage
- C. Reverse biasing the gate
- D. None of the above
Explanation
The firing instant, and therefore the conduction angle, is controlled by the gate trigger signal, commonly adjusted through gate voltage or current. Reverse-biasing the gate is not the normal method of controlling turn-on angle.
