1. An electric power generator for an aircraft, comprising:
a two-stage variable-frequency generator including a main generator, a permanent magnet exciter, a rotating bi-directional AC/DC/AC electric power converter system, and a controller;
wherein the rotating bi-directional AC/DC/AC electric power converter system is coupled to a rotatable shaft;
wherein the rotating bi-directional AC/DC/AC electric power converter system includes a first rotating bi-directional electric power converter for AC/DC conversion and a second rotating bi-directional electric power converter for DC/AC conversion;
wherein the first rotating bi-directional electric power converter and the second rotating bi-directional electric power converter are disposed adjacent to one another along the rotatable shaft; and
wherein the first rotating bi-directional electric power converter is electrically coupled to the second rotating bi-directional electric power converter via a DC power link.
