STATE-OF-THE-ART VFD CONTROL PANELS FOR IMPROVED MOTOR VELOCITY MANAGE BY UAE SUPPLIERS

voltage pulses of different lengths to simulate a sinusoidal wave. Ideally, the pulses are timed so that the time regular integral of the generate yields a great sinusoid. The present method of decision to produce this waveform operates a triangle wave and sine wave by way of a comparator, and outputs a voltage pulse Anytime the sine wave’s value
