Abstract
An output voltage of a plurality of chopper circuits is controlled by the average value of ON duties of their respective semiconductor switching elements so that there are provided a shunt controller which detects respective reactor currents of the plurality of chopper circuits and carries out shunt control based on the detected reactor currents and a voltage controller which carries out voltage control based on the detected output voltage, wherein a configuration is such that a control device controls the output voltage so that the reactor currents of the plurality of chopper circuits are equal to each other so as to prevent the average value of the ON duties of the semiconductor switching elements from changing due to the shunt control.
