Abstract
An object of the present invention is to provide an AC generator output controlling apparatus which can appropriately control the generating operation timing of an AC generator and which can prevent excessive load on an internal combustion engine due to the unnecessary generating operation of the AC generator. The output controlling apparatus has an AC generator driven by an internal combustion engine to generate an AC voltage, a rectifier for converting the generated AC voltage into a DC voltage, a battery charged by the converted DC voltage, and a charge control circuit for determining a duty for a field current supplied to a field coil of the AC generator from the battery on the basis of a voltage deviation between the charged DC voltage and a predetermined target voltage of the battery, and stopping the supply of the field current when the duty amount is lower than a predetermined value.
