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.

Claim (Index 1):
A multiphase converter comprising:\n a plurality of voltage conversion units; and a control unit configured to output PWM signals to the voltage conversion units to control the voltage conversion units individually, wherein the control unit includes:\n a signal control unit configured to output PWM signals to the respective voltage conversion units, and change, during a predetermined test period, a duty ratio of the PWM signal that is output to a target voltage conversion unit or a target group of voltage conversion units that is to be subjected to a test operation; \n an abnormality identifying unit configured to identify, from among the plurality of voltage conversion units, an abnormal voltage conversion unit or a group including the abnormal voltage conversion unit subject to a predetermined abnormal state with respect to at least one of an electric current, a voltage, and a temperature during the test period; and \n an operation control unit configured to cause, if the abnormality identifying unit has identified an abnormal voltage conversion unit or group, any remaining voltage conversion unit of the plurality of voltage conversion units other than the identified abnormal voltage conversion unit or group including the abnormal voltage conversion unit to perform voltage conversion.
