SUPERIOR VFD CONTROL PANELS FOR PRICE TAG-POWERFUL MOTOR SPEED REGULATION IN UAE INDUSTRIES

voltage pulses of various lengths to simulate a sinusoidal wave. Preferably, the pulses are timed so that the time regular integral on the travel yields a perfect sinusoid. The current technique of decision to provide this waveform operates a triangle wave and sine wave via a comparator, and outputs a voltage pulse Each time the sine wave’s value
