BEST VFD PANELS FOR COST-PRODUCTIVE SPEED REGULATION IN UAE INDUSTRIES

voltage pulses of different lengths to simulate a sinusoidal wave. Ideally, the pulses are timed so that the time common integral on the travel yields a wonderful sinusoid. The current method of selection to provide this waveform runs a triangle wave and sine wave through a comparator, and outputs a voltage pulse When the sine wave’s value is gre
