Abstract
A power generation system includes a grid converter configured to convert AC power from a grid into grid-originated DC power. The power generation system also includes a source converter configured to convert power from a source into source-originated DC power. An intermediate bus is configured to receive the grid-originated DC power and the source-originated DC power; and an output converter is coupled to the intermediate bus and configured to provide output power. In the power generation system a number of phases of the grid-originated DC power is different from a number of phases of the output power.
