Patent ID: 8106524

Claim:
A capacitor-compensation-type generator having a rotor wound with a field winding that is short-circuited with a diode, a stator wound with an output winding that is adapted to cross flux generated by the field winding to output AC power and with an exciting winding that is disposed at predetermined phase angle with respect to the output winding and is short-circuited with a phase advance capacitor, and an internal combustion engine that drives the rotor to rotate relative to the stator, comprising: an engine speed detector that detects a speed of the engine; an output voltage detector that detects output voltage of the AC power outputted from the output winding; an actuator that changes the engine speed; an actuator controller that controls operation of the actuator in accordance with one of a constant voltage operation mode in which the detected engine speed is controlled to a desired speed such that the detected output voltage becomes a desired voltage, and 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; and an operation mode selector switch adapted to be operated by a user for selecting one of the constant voltage operation mode and the constant frequency operation mode.
