ABSTRACT:
A three-phase flat-top waveform generator which may be utilized in a pulse-width modulator. Transfer function means receive a three-phase input signal and produce therefrom a zero sequence signal. Under steady-state and balanced conditions, the zero sequence signal will generally have a fundamental frequency three times the frequency of the input signal. Summing means add the zero sequence signal to each phase of the input signal to produce the desired flat-top signal.
