Abstract
A multi-phase converter has a plurality of voltage converter circuits connected in parallel; current sensors provided in the voltage converter circuits respectively; and a controller configured to calculate an estimated value of a total input current inputted to the multi-phase converter. The controller may be configured to output a notification signal that indicates an abnormality in one of the current sensors when a difference between a total sum of measured values of all the current sensors and the estimated value is outside a predetermined allowable range.
