摘要： Even in a situation other than engine normal operation such as engine stall, the output voltage of the three-phase brushless motor is prevented from causing the excessive voltage to be applied to an external load. A brushless motor control apparatus (10) of the present invention calculates the number of rotations of an engine based on a cycle of zero-cross points of the phase voltage Vsu induced to a sub-coil Su of a three-phase brushless motor (1). Then, when the number of rotation of the engine is smaller than the first number of rotations N1, before it becomes impossible to detect the zero-cross points, the control state of the three-phase brushless motor 1 is changed from the state of phase control by a phase control regulator unit (24) with respect to the AC output voltages Vu, Vv, and Vw to the state of interphase short circuit of motor coils by a short regulator unit (25). Then, when the number of rotations of the engine exceeds the first number of rotations No and the phase voltage Vsu becomes the voltage level such that the zero-cross points can be detected, the control state is changed again to the state of phase control by the phase control regulator unit (24).

摘要： The invention relates to a method for regulating a self-commutated converter that can be connected on the AC side to an AC network via an inductive component, wherein: an actual power value and an actual frequency value are determined from a network voltage measured on the AC side of the converter and from a converter current measured at the converter; an active power regulation difference is formed as the difference between an active power portion of the actual power value and a desired active power value, and a frequency regulation difference is formed as the difference between the actual frequency value and a predefined desired frequency value; an orthogonal portion of a converter control voltage is determined by means of an orthogonal regulator in accordance with the active power regulation difference, wherein an active power exchanged between the converter and the AC network is determined by means of the orthogonal portion, a parallel portion of the converter control voltage is determined by means of a parallel regulator in accordance with the active power regulation difference, wherein a reactive power exchanged between the converter and the AC network is determined by means of the parallel portion. The method is characterised in that the frequency regulation difference is supplied to the parallel regulator, such that the determining of the parallel portion of the converter control voltage is carried out in accordance with the frequency regulation difference. The invention also relates to a self-commutated converter for transmission with a regulation unit for regulating the transmitted power, which is designed to carry out the method according to the invention.

摘要： A generator controller provides independent and redundant overvoltage protection to an associated generator. The generator controller monitors the generator output at a first point of a regulation and a second point of regulation. A generator control unit (GCU) provides overvoltage protection based on the generator output monitored at the first point of regulation, including at least one of tripping a first generator control relay (GCR) to remove excitation from an exciter winding and tripping a generator line contactor (GLC) to disconnect the generator output from a bus. A overvoltage protection unit (OPU) provides independent, redundant protection based on the generator output monitored at the second point of regulation, including at one of tripping a second GCR to remove excitation from the exciter winding and tripping the GLC to disconnect the generator output from the bus.

摘要： An aircraft starting and generating system includes a starter/generator that includes a main machine, an exciter, and a permanent magnet generator. The system also includes an inverter/converter/controller that is connected to the starter/generator and that generates AC power to drive the starter/generator in a start mode for starting a prime mover of the aircraft, and that converts AC power, obtained from the starter/generator after the prime mover have been started, to DC power in a generate mode of the starter/generator. A main bridge gate driver is configured to drive a MOSFET-based bridge during start mode using Space Vector Pulse Width Modulation (SVPWM) and during generate mode using reverse conduction based inactive rectification.
