Concept:

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°.

\(V_{o(avg)} = {\sqrt{2}\times 230 \over 2\pi}(1+cos0)\)

\(V_{o(avg)}=\frac{\sqrt{2}\times230}{\pi}\)
