Abstract

In one aspect, there is provided a drive device (5) for a rotating electrical machine that drives a field winding-type rotating electrical machine (3) in which a rotor winding (316) is wound around a rotor core (312), the drive device (5) including: an electric circuit unit (60) between the rotating electrical machine (3) and a power supply; and a control device (150) that controls the electric circuit unit (60), the electric circuit unit (60) includes a smoothing capacitor (62) between a high-potential side line and a low-potential side line of the power supply, a power conversion circuit unit (63) that is electrically connected to both ends of the smoothing capacitor (62) and supplies alternating current power to a stator winding (312) of the rotating electrical machine (3), and a power supply circuit unit (64) that is electrically connected to both ends of the smoothing capacitor (62) in a manner parallel with the power conversion circuit unit (63) and configured to supply power to the rotor winding (316) and, the control device (150) includes a first control unit (155) that drives both the power conversion circuit unit (63) and the power supply circuit unit (64) when the smoothing capacitor (62) is discharged, a second control unit (156) that drives only one of the power conversion circuit unit (63) and the power supply circuit unit (64) when the smoothing capacitor (62) is discharged, and a selection unit (154) that selectively activates one of the first control unit (155) and the second control unit (156) based on a predetermined condition.
