Provided is a drive device for a rotary electric machine that minimizes variation in voltage, current pulse, and the like on the direct current side of an inverter, and that achieves a reduction of the capacity of a smoothing capacitor on the direct current side. The present invention relates to a drive device for a rotary electric machine that controls the driving of an alternating-current rotary electric machine. The direct current-side inductance (Ld) between the positive electrode of a direct current power supply and the positive electrode of the smoothing capacitor is switched by an inductance control unit between a predefined standard inductance (Ls) and a high inductance (Lh) that is higher than the standard inductance (Ls) in accordance with a switching frequency. |
