Abstract
An inverter for converting DC power into AC power includes first and second subinverters having a plurality of controllable switches and three-phase outputs coupled to a summing transformer having wye and delta connected sets of primary windings and a set of secondary windings. The switches in the subinverters are controlled so that the subinverters produce first and second sets of pulse-width modulated subinverter waveforms which are summed by the summing transformer to produce the AC power in the secondary winding.
