Abstract:
Provided is a multiphase DC-DC converter having a plurality of voltage conversion units, and detect an abnormality in any phase and to remain activated with a phase other than the faulty phase while the faulty phase is reliably protected. 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. Each of the voltage conversion units includes on an individual input path, a protective switch element, and a protective switch element disposed on an individual output path. The DC-DC converter further includes a protective abnormality identifying unit configured to identify a range in which a protective switch element is abnormal, and an operation control unit configured to cause, if the range in which a protective switch element is abnormal has been identified, any remaining conversion unit other than the range to perform a voltage conversion operation.

Claim (Index 2):
A DC-DC converter comprising:\n a multiphase conversion unit that is provided with a plurality of voltage conversion units that are arranged between an input-side conductive path and an output-side conductive path, each voltage conversion unit including an individual input path connected to the input-side conductive path, a conversion operation portion configured to convert a voltage input to the individual input path using an on/off operation of a driving switch element, and an individual output path serving as an output path for the voltage converted by the conversion operation portion, each voltage conversion unit being provided with, on at least one of the individual input path and the individual output path, a protective switch element configured to switch the corresponding individual input or output path between a conductive state and a non-conductive state; a protective abnormality identifying unit configured to identify at least either a conversion unit in which a protective switch element is abnormal, or a group including a conversion unit in which a protective switch element is abnormal, from among the plurality of voltage conversion units that constitute the multiphase conversion unit; and an operation control unit configured to cause, if a conversion unit in which a protective switch element is abnormal or a group including a conversion unit in which a protective switch element is abnormal is identified by the protective abnormality identifying unit, any remaining conversion unit other than the conversion unit or the group including the conversion unit that has been identified by the protective abnormality identifying unit to perform a voltage conversion operation.
