Abstract
Two inverters provided at respective both ends of open-end windings are appropriately controlled. A rotating electrical machine control device () that can control a first inverter () and a second inverter () by a plurality of control schemes, respectively, the control schemes differing from each other in at least one of a switching pattern and a switching frequency and being independent of each other, has a control mode in which the first inverter () and the second inverter () are controlled by the same control scheme in a first speed region (VR) in which the rotational speed of a rotating electrical machine (), and the first inverter () and the second inverter () are controlled by different control schemes in a second speed region (VR) in which the rotational speed of the rotating electrical machine () is higher than in the first speed region (VR).
