Abstract
Provided is a DC/DC converter device capable of suppressing overshooting of an output voltage and fluctuation of an input voltage. The DC/DC converter device includes: a DC/DC converter including a power conversion unit and a reactor; and a control unit. The control unit includes a rate-of-change limiting value setting unit configured to set a rate-of-change limiting value for the output voltage target value, and is configured to limit the output voltage command value by using the rate-of-change limiting value, to thereby generate the output voltage target value. The rate-of-change limiting value setting unit is configured to obtain an index value for quantitatively evaluating an amount of fluctuation in the input voltage, to thereby change a setting of the rate-of-change limiting value in such a direction as to narrow a rate-of-change limiting range when the index value is within a predetermined specific range.
