The most suited gate pulses given to the AC regulator with R - L load can be in the form of____________?
Correct answer: C. A train of pulses
- A. Continuous signal
- B. Large isolating pulse transformer
- C. A train of pulses
- D. None of these
Explanation
With an R-L load, the thyristor current may continue after the supply voltage changes sign, so a train of gate pulses gives reliable triggering when the device becomes forward biased. A single pulse may occur too early to trigger it.
