To provide a rotary electric machine apparatus which can perform current control which reduces a torque ripple component effectively, using a rotary electric machine in which the permanent magnet of the rotor has the skew structure which shifts the magnetic pole position in the circumferential direction at each position in the axial direction. When defining, as the current vector of most advanced phase, a current vector of current command values calculated on the dq-axis rotating coordinate system of most advanced phase, and defining, as the current vector of middle phase, a current vector of current command values calculated on the dq-axis rotating coordinate system of middle phase, the rotary electric machine apparatus brings a controlling current vector close to the current vector of most advanced phase from the current vector of middle phase, as the winding currents increase.

A control circuit for a power converter that configures a system that is mounted to a vehicle and includes a rotating electric machine that has multiple phases and includes a rotor that is capable of transmitting power to and from a drive wheel, and the power converter that includes upper- and lower-arm switches that are electrically connected to phase windings of the rotating electric machine. The control circuit determines whether an abnormality has occurred in the system, determines whether the system has been started based on an output voltage of the insulating power supply, and performs short-circuit control to turn on an on-side switch that is either one of the upper- and lower-arm switches and to turn off an off-side switch that is the other of the upper- and lower-arm switches, in response to the system being determined to have been started, and the abnormality being determined to have occurred.
