Abstract
A system, apparatus, and/or method for an aircraft that provides a novel independent-speed variable-frequency generator for aviation power generation. The generator architecture utilizes a 2-stage generator architecture with a wound rotor PM exciter (PME) that provides excitation to the rotor of a generator. A rotating bi-directional AC/DC/AC electric power converter connects the rotor windings of the exciter and the generator.
