ABSTRACT:
A vehicular generator unit includes an alternator and a generator control system that controls the alternator. The alternator is driven by an engine to achieve the power generation for charging a battery. The generator control system includes a transistor for intermitting a field current therethrough so as to control the power generation of the alternator. The system further includes a switching circuit which suppresses the duty of the transistor to a low value, where the alternator can not perform the power generation for the battery, until complete engine start-up or self-rotation is detected. On the other hand, when start-up is detected, the duty of the transistor is switched to a value where the alternator can perform the power generation for the battery. The duty of the transistor is then increased gradually to 100%.
