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.
