Abstract
A power generation control system for a vehicle generator comprises a generator including an armature coil, an exciting coil and a rectifier for rectifying the AC output of the armature coil, a battery, and a voltage control device for controlling the activation of the generator in accordance with the terminal voltage of the battery. This power generation control system further comprises an abnormal voltage detector circuit for detecting the voltage generated across the armature coil and cutting off the current flowing in the exciting coil when said voltage exceeds a predetermined value. The abnormal voltage detector circuit has the function to hold this forcible stoppage of power generation.
