ABSTRACT:
A highly reliable control system for AC generator capable of reducing such adverse effects as belt slippage or a drop in engine rpm's of a vehicle due to an abruptly increased torque of the AC generator. The system comprises: a rectifier 2 for rectifying an AC output of the AC generator 1 having a field coil 102; a storage battery 4 to be charged by a rectified output of the rectifier 2; an output changeover controller 7 for switching between the storage battery and a load to be driven by a voltage higher than a normal output voltage at the time of charging the storage battery; and a voltage regulator 3A for intermittently controlling a field current flowing through the field coil 102 to adjust voltage of the storage battery 4 in a first operation mode for charging of the storage battery and to adjust output voltage of the AC generator 1 in a second operation mode which is a high voltage operation, respectively, to predetermined values in the respective operation modes whereby the ON period in the intermittent control of field current is gradually increased when switching from the first operation mode to the second operation mode.
