A control apparatus is to drive a power converter. The power converter has a power supply unit, a switching member electrically connected to the power supply unit, and a power accumulator electrically connected to the switching member. The control apparatus controls a rotary machine with a terminal electrically connected to the power accumulator. A calculator calculates, based on a command voltage to the rotary machine, a command value for an output current to the power accumulator and the rotary machine. A chopper control unit carries out chopper control of the power converter by switching on and off the switching member based on the command value for the output current to thereby convert a voltage across the power accumulator into a desired voltage relation to a voltage of the power supply unit.
