摘要： A control apparatus of an AC generator for a vehicle can obtain large regeneration energy without making the size of the generator large. In the control apparatus in which an AC output current is rectified and supplied to a vehicle mounted battery (6) and an electric load of the vehicle, provision is made for a regulator (5) that controls a continuity rate of electric power supply to a field coil (3) of a generator (1) by controlling an output voltage of the generator (1). The regulator (5) suppresses the continuity rate of electric power supply to the field coil (3) at the time of steady operation of the vehicle, and switches a suppression value of the continuity rate of electric power supply so as to increase the continuity rate of electric power supply at the time of deceleration operation of the vehicle.

摘要： The control device including: a power transistor (502) for controlling conduction/non-conduction of a field coil (3) in accordance with an output voltage of an AC generator (1) mounted on a vehicle; an RPM detection section (511) for detecting an RPM of the AC generator (1); a drive duty setting section (510) for determining whether or not the RPM detected by the RPM detection section (511) is equal to or higher than a predetermined threshold, and reducing a conduction ratio of the field coil (3) when determining that the RPM is equal to or higher than the predetermined threshold; and a driver (504) for driving the power transistor (502) based on the conduction ratio. In this manner, the conduction ratio of the field coil (3) is reduced to suppress the drive torque.
