SUPERIOR-EFFECTIVENESS VFD HANDLE PANELS FOR SPECIFIC INDUSTRIAL MOTOR PACE REGULATION

voltage pulses of various lengths to simulate a sinusoidal wave. Ideally, the pulses are timed so that the time typical integral with the drive yields a wonderful sinusoid. The present means of decision to produce this waveform runs a triangle wave and sine wave through a comparator, and outputs a voltage pulse Any time the sine wave’s value is g
