HIGH-PERFORMANCE VFD PANELS FOR ENERGY-ECONOMICAL PACE MANAGE IN UAE

voltage pulses of different lengths to simulate a sinusoidal wave. Preferably, the pulses are timed so the time average integral from the drive yields a great sinusoid. The existing way of choice to make this waveform runs a triangle wave and sine wave via a comparator, and outputs a voltage pulse Every time the sine wave’s worth is greater compa
