<p>PROBLEM TO BE SOLVED: To provide a vehicle AC generator which can reduce and smooth the drive torque fluctuation of an alternator to suppress the hunting phenomenon of the revolutions in an idling state. SOLUTION: A sudden torque change region shifting means 147 for shifting the revolutions region of a vehicle AC generator, in which the driver torque of a generator changes suddenly as the result of the increase of the duty ratio of a switch 149 caused by the shortage of the power generating capability owing to the decline of the revolutions of a vehicle AC generator, to a low revolution side in accordance with revolutions-linked electric values is provided. More preferably, the sudden torque change region shifting means 147 shifts the revolutions region to the low revolutions side by changing an adjustment voltage in accordance with the revolutions-linked electric values when the revolutions are declined.</p> |
