For the half-wave rectifier, the output is present is only for one half of the input signal and clipped for the other half.
Positive half-wave rectifier clips the negative half of the input signal and only a positive part of the input signal is present. Negative half-wave rectifier clips the positive half of the input signal and only negative part of the input signal is presentIn a half-wave rectifier circuit, the average value of output voltage is:
${\mathrm{V}}_{\mathrm{avg}}=\frac{{\mathrm{V}}_{\mathrm{m}}}{\mathrm{\pi }}$
The RMS value of the output voltage is:
${\mathrm{V}}_{\mathrm{rms}}=\frac{{\mathrm{V}}_{\mathrm{m}}}{2}$
Where ${\mathrm{V}}_{\mathrm{m}}$ is the maximum value of supply voltage
