摘要： An aircraft electrical system comprises a generator to be driven as part of a gas turbine engine. The generator supplies electrical power to a plurality of accessories associated with the gas turbine engine, and to an aircraft DC bus in parallel to the supply to the accessories. A battery supplies voltage to a control circuit for the generator through a selectively opened and closed switch. A control detects a short circuit on the aircraft DC bus. The battery switch allows power from the battery to flow to provide control voltage for the generator when the control detects a short circuit on the aircraft DC bus.

摘要： An aircraft electrical system comprises a generator to be driven as part of a gas turbine engine. The generator supplies electrical power to a plurality of accessories associated with the gas turbine engine, and to an aircraft power bus in parallel to the supply to the accessories. A control detects a short circuit on the aircraft power bus. When a short circuit is detected on the aircraft power bus, a switch is driven open to disconnect the aircraft power bus from the generator. In this manner, the power will continue to be delivered to the plurality of accessories. In a separate feature, a control voltage is provided by an auxiliary permanent magnet generator to a voltage regulator for the main generator.

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 position sensing system for generating a rotor position signal that is representative of the angular position of the PM rotor; a control coil current sensor for generating a control coil current signal that is representative of the level of electrical current in the control coil; an electrical potential sensor for generating a DC bus potential signal that is representative of the level of DC potential on the DC bus; an electrical current sensor for generating a DC bus current signal that is representative of the level of DC current that the active rectifier supplies to the electrical load by way of the DC bus; an output power estimator that compares the DC bus potential signal with the DC bus current signal to generate an output power signal; a differentiator that receives the output power signal to generate a respective rate of output power signal; a summer that adds the rate of output power signal with the DC bus potential signal to generate a DC potential feedback signal; and a selectable main active/passive rectifier system for converting multiphase AC power developed by the stator to DC power supplied to the electrical load by way of a DC bus; 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 the control coil current signal and a DC bus potential feedback loop that comprises the 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 the rotor position feedback loop; and wherein both the control coil current regulator system and the 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.
