ABSTRACT:
A control apparatus of an AC generator for use in vehicles is disclosed which includes an AC generator having a field coil, a storage battery to be charged by a rectified output of the AC generator, a voltage regulator for regulating the output voltage of the AC generator and an excessive temperature controller that includes a triangular wave generator, a temperature detection circuit and a comparator. The controller controls the on-time ratio of a power transistor so that the field current flowing through the field coil is changed in accordance with output of the comparator which compares the output level of the temperature detection circuit and the triangular wave output of the triangular wave generator.
