摘要： An electromechanical power transfer system that transfers power between a prime mover and a direct current (DC) electrical power system, comprises: a permanent magnet machine (PMM) that has a permanent magnet (PM) rotor coupled to the prime mover, a stator with a multiphase alternating current (AC) winding coupled to an AC bus and a control coil with a winding that has a configuration to generate a magnetic field with flux that varies the reactance of the stator winding with the application of control coil current; a control coil current regulator system to regulate the control coil current; wherein the control coil current regulator system generates a level of the control coil current that regulates current in the stator to a desired level in response to a control coil current feedback loop that comprises a control coil current signal and a DC bus potential feedback loop that comprises a DC potential feedback signal and in a generating mode the main active rectifier system maintains a constant potential on the DC bus regardless of sudden changes in electrical load on the DC bus in response to the DC bus potential feedback loop and a rotor position feedback loop; and wherein both the control coil current regulator system and a main active rectifier system switch from an active regulating mode to a protection non-regulating mode upon detection of a fault in the DC bus.

摘要： A high frequency starter-generator system uses an electric machine design that does not employ rotating rectifiers installed on the rotor. The output frequency of such a starter-generator is increased by about 200% as compared with a conventional starter-generator with the same number of poles operating in the same speed range. This design allows significant weight and volume reductions of the electric machine while its reliability is increased. The present invention may find application in any starter-generator application, including more electric architecture-type aircraft designs currently in development.
