The average output voltage of a 1ϕ half-wave rectifier is given by:
\(V_{o(avg)} = {V_m \over 2\pi}(1+cosα)\)
where, Vo(avg) = Average value of output voltage
Vm = Maximum value of the input voltage
α = Firing angle
Calculation:
Given, Supply voltage = 230 V (RMS)
\(V_m = \sqrt{2}\times230\)
The maximum value of output voltage is achieved at α = 0°.
\(V_{o(avg)} = {\sqrt{2}\times 230 \over 2\pi}(1+cos0)\)
\(V_{o(avg)}=\frac{\sqrt{2}\times230}{\pi}\)
