Abstract
A vehicle-mounted electric rotating machine includes a field winding wound on a rotor for magnetizing a field pole of the rotor, a stator winding for generating an AC voltage in accordance with a rotating magnetic field generated by the field pole, a power converter for converting the AC voltage to a DC voltage and outputting the DC voltage through a first power supply line connected to an output terminal thereof, and a load dump handling section for performing a load dump protection operation when a voltage of the output terminal of the power converter exceeds a threshold voltage. The load dump handling section is supplied with operating power through a second power supply line provided separately from the first power supply line.
