Question

An SCR has the peak forward voltage = 1000 V. Find the maximum voltage that the SCR can handle if employed in a M-2 type full controlled converter circuit. Use factor of safety (FOS) = 2.5

(a) 500 V

(b) 400 V

(c) 200 V

(d) 1000 V

I had been asked this question in a dream while sleeping

I would like to ask this question from Single Phase FW AC-DC-3 topic in division Converters of Power Electronics

Answer 1

Right answer is (c) 200 V

The best I can explain: In M-2 type configuration maximum voltage handled is 2Vm

Therefore, 1000/2×2.5 = 200 V.
