Claim Text:
1. A system comprising: a generator; an AC/DC converter coupled with the generator; a DC bus coupled with the AC/DC converter; an inverter coupled with the DC bus, the inverter including a first leg, a second leg, and a third leg, each of the legs including a plurality of switching devices; an output circuit including a first system output coupled with the first leg, a second system output coupled with the second leg, and a third system output coupled with the third leg; a first controller configured to provide a first control signal to the switching devices of the first leg based upon a first voltage between the first system output and the third system output and a first current provided to the first system output; a second controller configured to provide a second control signal to the switching devices of the second leg based upon a second voltage between the second system output and the third system output and a second current provided to the second system output; and a third controller configured to provide a third control signal to the switching devices of the third leg to provide an output equal to one half of the DC bus voltage.
