Question

A single-phase half wave circuit has Vs = 230 V with a R load of 100 Ω. Find the average load current at α = 30°.

(a) 1.45 A

(b) 0.57 A

(c) 0.96 A

(d) 2.3 A

This question was addressed to me in a job interview.

This key question is from Single-Phase HW AC-DC-2 topic in chapter Converters of Power Electronics

Answer 1

Right answer is (c) 0.96 A

The explanation is: Io = Vo/R

Vo = (Vm/2π) x (1+cosα).
