VEHICLE-MOUNTED ELECTRIC ROTATING MACHINE
First Claim
1. A vehicle-mounted electric rotating machine comprising:
- 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 first threshold voltage, the load dump handling section being supplied with operating power through a second power supply line provided separately from the first power supply line.
