<p>PURPOSE:To provide an alternator output voltage control device which controls alternator output voltage in order to surely suppress a fluctuation of a speed of an internal combustion engine. CONSTITUTION:A control device is constituted of an alternator 11 driven by an internal combustion engine, IC regulator 13 for controlling voltage, with which a battery 12 is charged, to predetermined reference voltage by controlling field current duty, ratio means 14 for detecting the field current duty ratio, means 15 for discriminating whether a periodically changing electric load is actuated or not and a means 16 for fixing the duty ratio of a field current in the case of discriminating the electric load actuated.</p> |
