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

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

Right Answer is:

400/π

SOLUTION

The average output voltage of 1φ, half wave controlled rectifier is

Vo = (Vm/2π) x (1+cosα)

Where

Vm = Maximum voltage

Vm = 400

400/2π x (1+cos60) = 300/π.
