POWER GENERATION CONTROLLER FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a power generation controller for a vehicle in which the limiting operation of a field current can be eliminated in response to a necessity while the power generating state of a generator for the vehicle is maintained. SOLUTION: The power generation controller 1 for the vehicle comprises an FET 11 for intermittently interrupting the field current, a reflux diode 12, a voltage control circuit 13 for controlling the ON/OFF state of the FET 11 so that the output voltage of the generator 2 for the vehicle becomes a predetermined regulating voltage set value, a field current suppressing circuit 14 for suppressing the accelerating speed of the current flowing to a field winding 22, a charge lamp drive circuit 15 for driving a charge lamp 6, and an inhibiting circuit 16 for inhibiting the suppressing operation of the accelerating speed of the current by the suppressing circuit 14. When an L terminal voltage is a reference voltage Vc or more, the inhibiting circuit 16 is operated, and the functions of the field current suppressing circuit 14 and the charge lamp drive circuit 15 are eliminated.
