Abstract
A system comprises a first 3-phase rectifier having a positive DC lead and a negative DC lead and a second 3-phase rectifier having a positive DC lead and a negative DC lead. The system also includes a 4-phase, 3-level inverter connected to the first and second 3-phase rectifiers. A method comprises receiving variable frequency, 3-phase power from a first generator, receiving variable frequency, 3-phase power from a second generator, rectifying the variable frequency, 3-phase power from each of the first and second generators into DC power. And inverting the DC power into 4-phase, constant frequency power for powering a load.
