Abstract:
1. An apparatus for a multiphase converter for controlling a fuel cell output, which controls driving of each phase by shifting the phase, comprising a controller that includes: a driving frequency control device which sets a driving frequency of a converter in a case of single-phase driving of the multiphase converter higher by a predetermined amount than a driving frequency of the converter in a case of multiphase driving, and a determining device which determines a number of driving phases of the multiphase converter in accordance with a size of a load connected to the multiphase converter, wherein the controller is programmed to control the driving frequency control device to set the driving frequency of the converter in the single-phase driving on a basis of a predetermined desired size of a ripple current and a predetermined desired size of a switching loss generated in the single-phase driving.
