Silicon controlled rectifier can be turned on____________?
Correct answer: A. By applying a gate pulse and turned off only when current becomes zero
- A. By applying a gate pulse and turned off only when current becomes zero
- B. And turned off by applying gate pulse
- C. By applying a gate pulse and turned off by removing the gate pulse
- D. By making current non zero and turned off by making current zero
Explanation
An SCR is triggered into conduction by a gate pulse, but the gate cannot turn it off. It turns off only when anode current falls below the holding current, usually at a natural current zero.
