1. A rotating machine control device for driving one or more multi-phase rotating machines including one or more multi-phase winding sets and one or more direct-current rotating machines having one end as a first terminal connected to a phase current path in one or more phases of at least one set of the one or more multi-phase winding sets, the rotating machine control device comprising:
one or more multi-phase power converters that is connected to a positive electrode and a negative electrode of a power supply via a high potential line and a low potential line, respectively, converts a direct current electric power of the power supply to a multi-phase alternating current electric power according to an operation of a plurality of inverter switching elements bridge-connected to each other, and applies a voltage to each phase winding of the one or more multi-phase winding sets;
a direct current rotating machine switch that includes a high-potential side switch and a low-potential side switch connected in series to each other via a direct current motor terminal connected to a second terminal which is an other end opposed to the first terminal of the one or more direct-current rotating machines, and sets a voltage of the direct current motor terminal to be variable by switching; and
a control unit that controls an operation of the plurality of inverter switching elements and the direct current rotating machine switch in a drive circuit for the one or more multi-phase rotating machines and the one or more direct-current rotating machines, wherein:
the drive circuit includes the one or more multi-phase power converters and the direct current rotating machine switch;
the control unit includes an anomaly detection unit for detecting an anomaly of the one or more multi-phase power converters or the one or more multi-phase rotating machines, or an anomaly of the direct current rotating machine switch or the one or more direct-current rotating machines; and
the control unit changes a switching operation of the plurality of inverter switching elements and the direct current rotating machine switch according to the anomaly detected by the anomaly detection unit.
