ABSTRACT:
The stator of the vehicle-mounted alternator includes a stator core formed with a plurality of slots located along a circumferential direction thereof, and first and second multi-phase windings wound in the slots, the first and second multi-phase windings being spaced from each other by a predetermined electrical angle. An output of the first multi-phase winding is rectified by a first rectifier device, and an output of the second multi-phase winding is rectified by a second rectifier device. The second rectifier device is constituted by a plurality of switching devices. The vehicle-mounted alternator includes a control device to perform on/off control on the switching devices such that a phase angle difference between an output of the first rectifier device and an output of the second rectifier device is varied depending on a rotation speed of the stator.
