Abstract: This invention relates to the use of a magnetic sensing device for monitoring the magnetic flux condition in the core of an inverter output transformer as a means for developing an inverter control feedback signal indicative of an unbalance in the magnetic flux between alternate half cycles of an inverter AC output voltage waveform developed across the output transformer.

Abstract: The invention comprises apparatus for comparing the filtered power transformer output waveform of a pulse-width-modulated inverter circuit with an AC reference voltage waveform and generating output voltage signals to control the inverter drive circuit to the extent necessary to produce an inverter output waveform substantially duplicating the reference voltage waveform and substantially void of low order harmonics. An anticipatory signal developed by a circuit which monitors the change in current with respect to time in a capacitor included in a filter circuit connected to the output of the power transformers provides optimum response of the apparatus to changes in the output waveform beyond prescribed units relative to the reference voltage waveform.
