| titleOfInvention | Rotating electrical machine control system |
| abstract | In a rotating electrical machine control system, it is possible to achieve both improvement in controllability in pulse current superimposition control and suppression of switching loss and element overheating. A rotating electrical machine control system includes a rotating electrical machine and a control device that controls the rotating electrical machine. The control device 46 includes an inverter signal generation unit 52 that generates an inverter switching signal according to a current command and a carrier having a predetermined waveform, a pulse current superimposition unit 48 that superimposes a pulse current on the current command, and a carrier that sets a carrier frequency. And a frequency setting unit 50. The carrier frequency setting unit 50 makes the carrier frequency higher than the carrier frequency when the pulse current is not superimposed when the pulse current is superimposed on the current command.
