  • Power generation controller for AC generator
    Patent number: 7023102
    Abstract: A power generation controller for an AC generator detects the state of a battery and an electric load to control the output of the AC generator. A current detector detects a current to be used by an electric load on the vehicle. The controller includes a field current control section, a field current monitor section, and an output control section. The field current control section controls a field current of the AC generator. The field current monitor section monitors a field current duty value which is a controlled state of the field current of the AC generator. The output control section corrects the output of the AC generator according to the field current duty value, monitored by the field current monitor section, and/or the load current value, detected by the current detector.
