VFD - 36 Pulse Unit Advantages

  1. Jan 22, 2010 #1
    Hi,

    I would like to ask if anyone with VFD and PWM - Invertor knowledge could give me a run down on the advantages of a 36 Pulse VFD Unit in comparison to a 12 Pulse? Is the cancellation of harmonics a factor in Pulse selection?

    Thankyou

    The more pulses you have the better you can approximate the sinusoidal wave. And the more pulses you have the lower the harmonic distortion.
