Abstract
A charging generator for a vehicle including a field winding rotated by the rotation of an engine so as to generate a rotating magnetic field; an armature winding responsive to the rotating magnetic field to generate a current and charge a battery via a rectifier; a comparison circuit for comparing a voltage of the battery or a voltage of the rectifier with a predetermined value; a current control circuit for controlling a field current to be supplied to the field winding on the basis of output of the comparison circuit; a voltage change value detection circuit for detecting a change value in the battery voltage or the rectifier voltage; and a load response control circuit for suppressing a rise in the field current to be supplied to the field winding on the basis of an output of the voltage change value detection circuit.
