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.

摘要： A voltage regulator, an operation method thereof, and a voltage regulating system, and a mobile vehicle are provided. The voltage regulator coupled to an alternator and a battery includes a voltage detection unit which is coupled to the alternator and a startup assisting unit. The voltage detection unit operatively generates an enable signal responsive to an output voltage of the alternator. The startup assisting unit is coupled to the alternator, the battery, and the voltage detection unit. The startup assisting unit operatively generates a first exciting current to excite a rotor coil according to the enable signal. When the voltage detection unit detects that the output voltage is greater than a predetermined voltage threshold, the voltage detection unit outputs the enable signal causing the startup assisting unit to generate the first exciting current to the rotor coil, thereby facilitating the alternator to establish voltage under low rotational speed.
