MAJOR VFD CONTROL PANELS FOR ENERGY-PRESERVING INDUSTRIAL MOTOR PACE REGULATE

voltage pulses of different lengths to simulate a sinusoidal wave. Ideally, the pulses are timed so which the time regular integral on the travel yields an excellent sinusoid. The current approach to decision to make this waveform runs a triangle wave and sine wave by way of a comparator, and outputs a voltage pulse Anytime the sine wave’s worth
