Abstract

The present invention minimizes system loss during execution of intermittent boosting. A boost converter control apparatus has: a target value setting device for setting a target value of output voltage that minimizes a loss of a power supply system including a DC power supply, a boost converter, and a loading apparatus; an intermittent controlling device for executing an intermittent process of boost control in such a manner that the output voltage is maintained in a range including the set target value; an average value calculating device for calculating an average value of the output voltage in an execution period of the intermittent process; and a target value correcting device for correcting the set target value to reduce a deviation between the calculated average value and the set target value.
