Question

In case of an RC half wave triggering circuit, the firing angle can be ideally varied between

(a) 0 to 180

(b) 0 to 90

(c) 0 to 120

(d) 0 to 360

I have been asked this question during an interview.

This question is from Firing Circuits-2 topic in division Other Circuits of Power Electronics

Answer 1

Right option is (a) 0 to 180

To explain I would say: Unlike the R firing circuit, the RC firing circuits can be used to obtain firing angle greater than 180. Although practically 0 and 180 degree is improbable.
