Abstract
A rotating machine control device drives a multi-phase rotating machine and a direct-current rotating machine. The control unit controls an operation of an inverter switching element and a direct current rotating machine switch in a drive circuit of the multi-phase rotating machine and the direct current rotating machine. The control unit has an anomaly detection unit for detecting an anomaly in the multi-phase power converter or the multi-phase rotating machine, or an anomaly in a direct current rotating machine switch or the direct current rotating machine. The control unit changes the switching operation of the inverter switching element and the direct current rotating machine switch according to the anomaly.
