Question

Calculate the PIV for the Full-wave bridge rectifier if the peak value of the supply voltage is 50.

(a) 72.5 V

(b) 72.8 V

(c) 70.7 V

(d) 76.1 V

I had been asked this question in a national level competition.

Origin of the question is Electrical Drive Systems and Components topic in division Electrical Drive Systems and Components of Electric Drives

Answer 1

Correct answer is (c) 70.7 V

The explanation is: The peak inverse voltage for the Full-wave bridge rectifier is Vm = √2×230=70.7 V. The peak inverse is the maximum negative voltage across the thyristor.
