Abstract
A control device for an alternating current generator of a vehicle, having a storage battery which is charged by a rectified output of the generator, a field current detecting resistance (304) having a positive temperature coefficient, a voltage divider (305, 306) for setting a reference voltage, and a comparator (307) for comparing the potential drop across the current detecting resistance with the reference voltage to thereby control the field current duty cycle. The voltage divider includes a compensating resistor (319) to change the reference voltage in accordance with temperature.
