EXCELLENT VFD CONTROL PANELS FOR COST-POWERFUL MOTOR SPEED OPTIMIZATION IN UAE

voltage pulses of different lengths to simulate a sinusoidal wave. Preferably, the pulses are timed so the time normal integral in the generate yields a wonderful sinusoid. The present method of preference to produce this waveform runs a triangle wave and sine wave through a comparator, and outputs a voltage pulse Anytime the sine wave’s value is
