In a 1φ, half wave controlled rectifier if the input voltage is 400 sin314t, the average output voltage for a firing angle of 60° is

Question

RRB Paper · Accepted Answer

The average output voltage of a half-wave controlled rectifier can be calculated using the formula:

Vo = (Vm/π) * (1 - cosα)

where

Vm is the maximum voltage of the input waveform
α is the firing angle.

Substituting Vm = 400 V and α = 60°, we get:

Vo = (400/π) * (1 - cos 60°) = 300/π
