    Hi

    I would like some help with PWM.

    Could someone tell me what are the implications of the frequency index on the inverter voltage output if it is halved and again when it is doubled?

    Also is it preferable to compare the sinusoidal reference signal to a triangular signal to produce the PWM?


    Could anyone recommend helpful books that would help me with PWM?

    Thanks in advance.

    Hi,

    This sounds a lot like homework issued last week...
