Claim Text:
1. A control unit for a rotary electric machine that includes a plurality of winding units, each winding unit having a plurality of wirings correspondingly provided for a plurality of phases or terminals, the rotary electric machine being rotated by an electric power supplied from a first power supply, the control unit comprising: a plurality of power converting parts correspondingly provided for the plurality of winding units, each of the power converting parts converting the electric power supplied from the first power supply; a plurality of relays correspondingly provided for the plurality of power converting parts, each of the relays being disposed between the first power supply and a corresponding one of the power converting parts, and permitting or shutting off a flow of the electric power between the first power supply and the corresponding one of the power converting parts; a control part being operated by an electric power supplied from a second power supply, and controlling operations of the relays and the power converting parts to control the rotary electric machine; a boosting part having a first end and a second end, the first end being electrically connected between at least one of relays, excluding one relay among the plurality of relays, and the power converting part corresponding to the at least one of the relays, the second end being electrically connected to the control part, the boosting part boosting a voltage at the first end and outputting the voltage boosted from the second end; and an abnormality detecting portion detecting an abnormality of the boosting part, wherein when the abnormality detecting portion detects the abnormality of the boosting part, the control part controls the at least one of the relays, to which the first end of the boosting part is connected, to shut off a flow of the electric power from the first power supply to the boosting part and the power converting part corresponding to the at least one of the relays.
