Abstract
Provided is a multiphase converter having a plurality of voltage conversion units, and is configured to protect the faulty phase and continue driving using another phase when an abnormality occurs in any phase. A DC-DC converter includes a plurality of voltage conversion units that are in parallel between an input-side conductive path and an output-side conductive path. A control unit subjects the plurality of voltage conversion units to a test operation in which a duty ratio of a PWM signal for each voltage conversion unit is changed. The control unit identifies an abnormal voltage conversion unit based on at least one of the states of the electric current, the voltage, and the temperature of the multiphase conversion unit during this test period, and causes the remaining voltage conversion unit other than the identified abnormal voltage conversion unit to perform voltage conversion.
