Disclosed is a control device which performs voltage conversion control for a voltage conversion circuit between motor control circuits which control a plurality of motors and a power supply. The control device includes sampling means for sampling a DC voltage after voltage conversion, target voltage setting means for setting target voltages of the plurality of motors, selection means for selecting a target voltage to be converted by the voltage conversion circuit from among the plurality of target voltages, generation means for generating a sampling timing on the basis of a carrier signal of one of the motors having the unselected target voltage, and control means for performing voltage conversion control using the DC voltage sampled by the sampling means in response to the sampling timing for each sampling timing request of voltage conversion control.
