determine the form factor and peak

Question

Determine the form factor and peak factor:

Determine the form factor and peak factor for the above half rectified wave.

Solution

From the above example,

I _rms  = 0.5 I m

I _av        = I_m/ π

∴ Form factor = I_rms / I_av  = 0.5 I_m / (I_m/π)  = 1.57

and peak factor

=   I_m / I_rms =     I_m /0.5 I_m = 2
