QUALITY VFD PANELS FOR EXACT VELOCITY MANAGEMENT BY UAE ELECTRICAL PROFESSIONALS

voltage pulses of various lengths to simulate a sinusoidal wave. Preferably, the pulses are timed so the time typical integral from the travel yields a perfect sinusoid. The current means of choice to create this waveform operates a triangle wave and sine wave by way of a comparator, and outputs a voltage pulse Every time the sine wave’s value is
