ABSTRACT:
A charging generator output control system for automobiles is disclosed, in which the field current of the generator is controlled by a chopper, an output voltage of the generator is compared with a predetermined target voltage, the difference therebetween is detected, and the duty factor of an output signal of the chopper is controlled in accordance with the difference while at the same time controlling the frequency of an output signal of the chopper in accordance with the duty factor, thus reducing the difference substantially to zero.
