Abstract

A control device (60) is applicable to a system including: a rotary electric machine (20) having armature windings (24U, 24V, 24W) and a field winding (22), a storage unit (10) that stores the driving power for the rotary electric machine, a first power converter (31) electrically connected to the armature windings and which controls the current flowing through the armature windings, and a second power converter (33) electrically connected to the field winding and controls the current flowing through the field winding. The control device includes a first control unit that performs switching control of the first power converter in a state in which an AC power supply (41) is electrically connected to the storage unit via the armature windings and the first power converter so that a current flows from the AC power supply to the power storage unit, and a second control unit that performs switching control of the second power converter so that torque of the rotary electric machine generated during switching control of the first power converter is reduced compared to when no current flows through the field winding.
