Abstract:
1. A rotating electrical machine control system comprising: a rotating electrical machine that drives a vehicle; a frequency conversion portion provided between a DC power supply and the rotating electrical machine, the frequency conversion portion converts an output of the DC power supply to alternating current when the rotating electrical machine performs power running and converts an output from the rotating electrical machine to direct current when the rotating electrical machine performs regeneration; a voltage conversion portion provided between the DC power supply and the frequency conversion portion, the voltage conversion portion increases a voltage of the output of the DC power supply based on a boost command value set in accordance with a requested torque requested for the rotating electrical machine; a torque limitation portion that limits a torque of the rotating electrical machine; and an abnormality detection portion that detects an abnormality requiring the voltage conversion portion to be stopped, wherein when the abnormality detection portion has detected the abnormality:
