POWER-PRODUCTIVE VFD CONTROL PANELS FOR INDUSTRIAL VELOCITY REGULATION BY UAE PRODUCERS

voltage pulses of various lengths to simulate a sinusoidal wave. Ideally, the pulses are timed so which the time average integral on the generate yields a great sinusoid. The existing technique of decision to create this waveform operates a triangle wave and sine wave through a comparator, and outputs a voltage pulse whenever the sine wave’s valu
