1. A rotating machine control device configured to drive one or more multiphase rotating machines including one or more multiphase winding sets and a plurality of DC rotating machines in each of which a first terminal that is one end is connected to a phase current path of one or more phases of at least one of the multiphase winding sets,
the first terminal of each of two or more DC rotating machines of the plurality of DC rotating machines being connected to a phase current path of a same one phase of the multiphase winding set,
the device comprising:
one or more multiphase power converters that are connected to a positive electrode and a negative electrode of a power supply via a high potential line and a low potential line, respectively, convert DC power of the power supply into multiphase alternate current power by operations of a plurality of inverter switching elements connected in a bridge configuration, and apply a voltage to each of phase windings of the multiphase winding set;
a DC rotating machine switch made up of two or more legs, each of which is made up of switches on a high potential side and a low potential side connected in series via a DC motor terminal connected to a second terminal that is an end of the DC rotating machine on an opposite side to the first terminal, the DC rotating machine switch making a voltage of the DC motor terminal variable by switching; and
a control unit that controls operations of the inverter switching elements and the DC rotating machine switch.
