BEST VFD REGULATE PANELS FOR PRECISE MOTOR SPEED REGULATION IN UAE

voltage pulses of various lengths to simulate a sinusoidal wave. Preferably, the pulses are timed so which the time average integral from the drive yields a great sinusoid. The current means of choice to generate this waveform runs a triangle wave and sine wave through a comparator, and outputs a voltage pulse Each time the sine wave’s worth is b
