ABSTRACT:
A three-phase invertor and control is disclosed for synthesizing low harmonic content AC voltage in the non-linear, or overmodulation, region of inverter operation. A field orientation control provides a reference voltage vector representing the desired AC output voltage in magnitude and angle. Three state, two state, and step inverter operations are used individually and in combinations in accordance with magnitude and angle parameters of the reference voltage vector.
