Question

For a single phase, full bridge, diode rectifier excited from a 230 V, 50 Hz source. With R = 10 Ω & the inductance(L) large enough to maintain continues conduction, the average and rms values of diode currents will be

(a) 7.85 A, 8 A

(b) 10.35 A, 7.85 A

(c) 10.35 A, 14.6 A

(d) 8 A, 8 A

I have been asked this question during an interview.

The query is from 1P-Diode Rectifier FW-2 topic in division Diode Rectifiers of Power Electronics

Answer 1

The correct option is (c) 10.35 A, 14.6 A

Easiest explanation: Id(avg) = Io/2 = Vo/2R

Id(rms) = Io/√2 = Vo/R√2.
