FIND MAJOR VFD PANELS FOR INDUSTRIAL VELOCITY REGULATION BY UAE MAKERS

voltage pulses of various lengths to simulate a sinusoidal wave. Preferably, the pulses are timed so the time average integral on the travel yields an excellent sinusoid. The existing method of preference to produce this waveform operates a triangle wave and sine wave by way of a comparator, and outputs a voltage pulse Anytime the sine wave’s wor
