Split phase power conversion apparatuses, methods and systems

摘要

Split phase power conversion apparatuses, methods and systems are disclosed. One exemplary embodiment includes a generator, an AC/DC converter coupled with the generator, a DC bus coupled with the AC/DC converter, and an inverter coupled with the DC bus. The inverter includes first, second, and third legs each including a plurality of switches. A first controller provides a control signal to the first leg based upon a voltage between a first system output and a second system output and a first current provided to the first system output. A second controller provides a second control signal to the second leg based upon a voltage between the second system output and a third system output and a second current provided to the third system output. A third controller controls the third leg to provide an output equal to one half of the DC bus voltage.
