This multi-phase converter control device performs PWM control on driving of a multi-phase converter. The multi-phase converter is configured such that a plurality of converters connected to each other in parallel have reactors, and the reactors are magnetically coupled with each other and step up an input voltage to generate a step-up voltage. This multi-phase converter control device includes a feedback control unit configured to perform feedback control such that the step-up voltage is a target voltage, a PWM control unit configured to generate a PWM signal on the basis of a voltage command value output from the feedback control unit, and a drive unit configured to drive the multi-phase converter on the basis of the PWM signal. The feedback control unit calculates a step-up ratio of the multi-phase converter and changes a control gain in the feedback control on the basis of the step-up ratio.
