Claim Text:
1. A power conversion control device that electronically controls a power conversion circuit having an inductor, a power running-mode current restricting element, and a power regeneration-mode current restricting element, the power running-mode current restricting element and the power regeneration-mode current restricting element being connected to the inductor and each configured by a parallel circuit composed of a rectifying element and a switching element that is opened and closed by electronic control from outside, wherein: switching for switching control of the power conversion circuit from the complementary control to the power running control or the power regeneration control when it is judged that the direction is reversed, wherein the judgment is performed by judging whether or not an absolute value of an average value of the current flowing through the inductor is equal to or larger than ½ of a peak current based on a fluctuation amount of the current flowing through the inductor, and the switching is performed by switching the control of the power conversion circuit to the complementary control when it is judged that the absolute value of an average value of the current is equal to or larger than ½ of the leak current, and switch the control of the power conversion circuit to either the power running control or the power regeneration control.
