ABSTRACT:
When an engine key switch of a vehicle is closed, a rotor coil of a three-phase a.c. alternator adapted to charge a vehicle-mounted battery is excited by a first controlling circuit. Even with the closure of the engine key switch, the exciting current is restricted to a predetermined value by a second controlling circuit before the alternator has reached a predetermined operating state. The operating state of the alternator is monitored by detecting a voltage at the neutral point of a stator coil connected in star of the alternator.
