A summing circuit includes a first input coupled to the output of the first subinverter, a second input coupled to the output of second inverter and an output. A control circuit is coupled to the subinverters and operates the switches such that a summed AC waveform is produced at the output of the summing circuit. Each switch is subjected to only a portion of the DC voltage.
