A PI control section performs a PI control on a deviation which is a difference between a DC voltage command and a DC voltage, and outputs a d-axis current command value. A PI control section performs a PI control on a deviation which is a difference between the d-axis current command value and a d-axis current, and outputs a d-axis voltage command value. Based on the d-axis voltage command value and a q-axis voltage command value, a PWM control section outputs a switching control signal for controlling a switching operation of a converter. A voltage command computation section generates the DC voltage command based on the d-axis voltage command value.
