US 2009/0267353 A1 · CAPACITOR-COMPENSATION-TYPE GENERATOR

Abstract

In a capacitor-compensation-type generator having a rotor wound with a field winding, a stator wound with an output winding adapted to cross flux generated by the field winding to output AC power, and an internal combustion engine that drives the rotor to rotate relative to the stator, there are equipped with an actuator that changes the engine speed and an actuator controller that controls operation of the actuator in accordance with a constant voltage operation mode in which the engine speed is controlled to a desired speed such that a detected output voltage becomes a desired voltage, or a constant frequency operation mode in which the detected engine speed is controlled to a predetermined speed such that frequency of AC power outputted from the output winding becomes a desired frequency, thereby enabling to output AC power at constant voltage or frequency.
