    摘要： In a control system for a motor-generator capable of functioning as a three-phase magnet-type synchronous motor after starting of an engine and functioning as a brushless DC motor before starting of the engine, a rotated-position detecting device is arranged to detect an induced voltage in each of three-phase coils included in the motor-generator and to detect a rotated position of a rotor based on such induced voltage. Thus, the rotated position of the rotor can be detected without use of a sensor, whereby the operation for assembling the motor-generator can be simplified.

    摘要： A vehicle alternator control device (1) has a power transistor (11), a flywheel diode (12), a voltage control circuit (13), a primary power supply circuit (14), and a secondary power supply circuit (15). When the alternator 2 starts rotation, the secondary power supply circuit (15) drives the primary power supply circuit (14) when the alternator speed reaches a frequency (fs) equivalent to a speed higher than an engine idling speed. When the engine stops and the speed of the alternator (2) drops, the secondary power supply circuit (15) stops the primary power supply circuit (14) when the alternator speed reaches a frequency (fe) equivalent to a speed below the engine idling speed.

    摘要： A power electrical system is disclosed for a microturbine power generator (12, 14). The invention permits the microturbine to be started using an external DC power source (18). The DC voltage is converted to a variable DC voltage by means of a bi-directional buck-boost chopper circuit (30), DC bus (24) and a DC-to-AC converter (26). The DC-to-AC converter produces at its output a fixed voltage pattern whose frequency is gradually increased in concert with the DC voltage, to accelerate the microturbine from standstill to startup speed. Once the microturbine is started, the excitation is discontinued , and the DC bus (24) and DC-to-AC converter (26) are used to produce output AC power at a voltage level and frequency to match an electrical load (16).

    摘要： An electric starter/generator system for a turbine engine capable of transforming mechanical power from the turbine engine to electric power during a generate mode of operation and of transforming electric power from a low voltage dc source to mechanical power to drive the turbine engine during a start mode of operation, comprises a synchronous starter/generator (110) having a poly-phase wound stator (112), and a rotor (114) rotably positioned therein, the rotor (114) is drivably coupled to the turbine engine. The system establishes an electric field in the rotor (114) by excitation inverter (116), and directly coupled dc source (118). A means for energizing each of the poly-phase stator windings (112A, 112B, 112C) to drive the starter/generator as a motor is powered from battery (118). The inverter (124) establishes a rotating electric field in the stator whereby a constant torque is produced by the rotor to drive the turbine engine.
