    Abstract: An alternator includes an exciter field device generating an exciter magnetic field in a first air gap, an exciter armature device configured to rotate with respect to the exciter magnetic field and impart a first voltage in a first set of coils at the first air gap, a main stator device including a second set of coils, and a rotor field device configured to be energized by the first current in the first set of coils and generate a main magnetic field that imparts a second voltage on the main stator device at a second air gap. The main stator device and the exciter field device lie in on a common plane normal to an axis of rotation, and the exciter armature device is inwardly spaced from the exciter field device, main stator device, and the rotor field device.

    Abstract: 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.

    Abstract: The present disclosure relates to motor vehicles. The teachings thereof may be embodied in the operation and control of an externally excited electrical generator in an on-board electrical system of a motor vehicle. An example method may include: setting the excitation voltage within the scope of regulating an actual output voltage of the generator at a predetermined setpoint output voltage of the generator; evaluating load requirements of at least one peak load consumer supplied from the on-board electrical system; identifying exceptional situations based on the load requirements; and in the event of an exceptional situation, setting an associated temporary excitation output voltage of the generator.

    Abstract: 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.
