An ECU sets target value of a system voltage based on an electric power loss of a motor generator and an inverter and controls a voltage boost converter. The ECU calculates the target value of the system voltage using a function expression generated, for each operating point of the motor generator, by approximating a loss characteristic which represents change of the electric power loss with respect to change of the system voltage, by a quadratic expression or a linear expression of the system voltage.
