Abstract:
Described is an independent speed variable frequency generator system that may include a rotor and a stator. The system may further include a pilot generator stage including a magnetic field source positioned on the rotor and a set of pilot multiphase windings positioned on the stator. The system may also include a high frequency transformer stage including a first set of high frequency transformer multiphase windings positioned on the stator and a second set of high frequency transformer multiphase windings positioned on the rotor. The system may also include a main machine stage including a set of main field multiphase windings positioned on the rotor and a set of main armature multiphase windings positioned on the stator, where the second set of high frequency transformer multiphase windings are coupled directly to the set of main field multiphase windings. The system may include a generator control unit.

Claim (Index 10):
A method for independent speed variable frequency power generation comprising:\n generating a high frequency modulated multiphase power signal at a generator control unit positioned external to a rotor of an independent speed variable frequency generator, the high frequency modulated multiphase power signal including a main field multiphase power signal component, wherein generating the high frequency modulated multiphase power signal comprises opening and closing a plurality of switching circuits of a multiphase inverter in a pattern that generates the high frequency modulated multiphase power signal at a controller circuit of the generator control unit; transmitting the high frequency multiphase power signal from a stator to the rotor of the independent speed variable frequency generator via a high frequency transformer stage; generating an asynchronous rotating magnetic flux at a set of main field multiphase windings positioned on the rotor by applying the main field multiphase power signal component of the high frequency modulated multiphase power signal to the main field multiphase winding; and converting the asynchronous rotating magnetic flux into a main machine multiphase power signal at a set of main armature multiphase windings positioned on the stator; and before generating the high frequency modulated multiphase power signal:\n connecting a motor start driver to the set of main armature multiphase windings; \n opening the plurality of switching circuits to prevent output at the multiphase inverter; and \n sending a current pattern from the motor start driver through the set of main armature multiphase windings to generate a rotating magnetic flux pattern that causes the rotor to turn, enabling startup of an engine.
