The present application presents a power conversion control device that does not reduce electric power conversion efficiency. A mode judging section judges whether a direction of current flowing through an inductor has been reversed or not based on both an average value of current flowing through the inductor, the average value being calculated by an average current calculating section, and a difference (i.e peak current) between a maximum value and a minimum value of a current flowing through the inductor, the difference being calculated by a peak current calculating section. And then if the judging section has determined that the direction of current flowing through an inductor has been reversed, the power conversion control device makes the switching elements ON/OFF-operation corresponding to either one of a power running mode or an electric power regenerating mode.
