Question

Determine the average value of the form factor of a half wave rectifier for the alternating current represent by
a. i = 20sinwt
b. i = 30sinwt

Answer 1

a)

$\text{For half wave siniusoidal waveform}\\ i_{avg}=\dfrac{i_{max}}{2}\\ \text{Form factor}=1.57\\ i=20\sin\omega{t}\\ i_{max}=20A\\ i_{avg}=\dfrac{20}{2}=10A\\$ b)

$i=30\sin\omega{t}\\ i_{max}=30A\\ i_{avg}=\dfrac{30}{2}=15A\\$
