Half rectified sine wave

    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.
