ABSTRACT:
A control device of a vehicle-mounted, self-excited alternator for supplying a field current to its field coil and selectively a charge current to a battery and a power to a high voltage electric load of the vehicle comprises a field current detector for detecting field current flowing through the field coil and a field current limiter which includes a reference device for providing a fixed reference value, a comparator for comparing the field current detected by the field current detector with the fixed reference value and a voltage regulator control device responsive to an output of the comparator to control the voltage regulator to cut-off the field current when the field current detected is larger than the reference value.
