Question

A 3-phase bridge rectifier, has the average output voltage as 286.48 V. Find the maximum value of line voltage

(a) 100 V

(b) 200 V

(c) 300 V

(d) 400 V

I had been asked this question by my school principal while I was bunking the class.

This interesting question is from 3P-Diode Rectifiers-2 topic in section Diode Rectifiers of Power Electronics

Answer 1

Right option is (c) 300 V

For explanation I would say: Vo = 3Vml/π

Vml = (π x Vo)/3 = 300 V.
