LARGE-PERFORMANCE VFD PANELS FOR OPTIMIZING ELECTRICAL MOTOR EFFECTIVENESS IN UAE

voltage pulses of different lengths to simulate a sinusoidal wave. Ideally, the pulses are timed so which the time typical integral in the drive yields a perfect sinusoid. The present method of decision to provide this waveform runs a triangle wave and sine wave through a comparator, and outputs a voltage pulse whenever the sine wave’s price is g
