Patent ID: 8154230

Claim:
A control apparatus for driving a power converter having: a power supply unit, a switching member electrically connected to the power supply unit, and a power accumulator electrically connected to the switching member to thereby control a rotary machine with a terminal electrically connected to the power accumulator, the control apparatus comprising: a calculator configured to calculate, as a command value for an output current to the power accumulator and the rotary machine, the sum of a current value calculated based on a command voltage to the rotary machine and a current flowing through the terminal of the rotary machine; and a chopper control unit configured to carry out chopper control of the power converter by switching on and off the switching member to thereby convert a voltage across the power accumulator into a desired voltage relative to a voltage of the power supply unit, and to bring the output current to the power accumulator and the rotary machine to the command value calculated by the calculator.
