A control unit includes: control command generation means for generating a first control command and a second control command that specifies currents to flow through a first winding set and second winding set respectively; voltage calculation means for calculating a first voltage command from the first control command and calculating a second voltage command from the second control command; and first voltage application means and second voltage application means for applying voltages to the first winding set and the second winding set of a rotating machine on the basis of the first voltage command and the second voltage command, wherein discharge control for electric charge of a smoothing capacitor is performed while torque generated by current flowing from the smoothing capacitor to the first winding set and torque generated by current flowing from the capacitor to the second winding set are cancelled out with each other.
