A generator control system of a vehicle AC generator includes a field coil, a first polyphase armature winding, a second polyphase armature winding, a first rectifier connected to the first armature winding and a second rectifier connected to the second armature winding. The generation control system includes a power transistor connected with the field coil, a voltage regulator for controlling the power transistor, a voltage comparator for providing a pulse signal by comparing output voltage of one of phase-windings of the first armature winding with one of second phase-windings of the second armature winding and a counter circuit for driving the voltage regulator when the number of pulses of the pulse signal becomes larger than a predetermined value.
