Calculating Frequency and Form Factor for Half Rectified Sine Wave

[D44]

1. Calculate the waveform frequency and form factor of a half rectified sine wave

Ipk = Peak current = 11A
Tp = Pulse time of sine wave = 0.02s
T = Period = 0.035s


2. I have used the equations:

Irms = Ipk*sqrt(f*Tp/2)
Iave = (2*f*Ipk*Tp)/pi
f = 1/T


3. I have waveform frequency as 1/0.035 = 28.57Hz

I have Irms = 5.88A and Iave = 4.00A and therefore form factor = 5.88/4.00 = 1.47.

Does this look correct?

Thanks

Presumably your equations for Irms and Iave represent suitable approximations, in which case your results are good.
