Abstract:
A multiphase converter is provided with a multiphase conversion unit including a plurality of voltage conversion units; and a control unit configured to individually control the voltage conversion units using control signals. The control unit performs soft start control on the voltage conversion units by offsetting the time periods for individual voltage conversion units against each other. A detection unit detects a value reflecting an output current or an output voltage on a common output path from the plurality of voltage conversion units. The abnormality identifying unit identifies the abnormal voltage conversion unit or the abnormal group of voltage conversion units that generates an abnormal current or an abnormal voltage based on a result of detection by the detection unit during the time periods in which the soft start control is performed.

Claim (Index 1):
A multiphase converter comprising:\n a multiphase conversion unit provided with a plurality of voltage conversion units configured to convert an input voltage and output the converted voltage; a control unit configured to individually control the voltage conversion units using control signals so that their output is equal to a target value, and to subject, when operation of the multiphase conversion unit is started, the voltage conversion units to soft start control of gradually increasing the respective target value for their outputs, the control unit offsetting the time periods in which individual voltage conversion units or groups of voltage conversion units are subjected to soft start control against each other; a detection unit configured to detect a value reflecting at least one of an output current and an output voltage on a common output path from the plurality of voltage conversion units; an abnormality identifying unit configured to identify an abnormal voltage conversion unit or an abnormal group of voltage conversion units that generates an abnormal current or an abnormal voltage, based on a result of detection by the detection unit during the time periods in which the soft start control is performed by the control unit; and a storage unit configured to store, if any abnormal voltage conversion unit or abnormal group of voltage conversion units is identified by the abnormality identifying unit a predetermined number of times, abnormality identification information indicating the abnormal voltage conversion unit or the abnormal group of voltage conversion units that has been identified the predetermined number of times, wherein the control unit disables, if the abnormality identification information is stored in the storage unit, execution of voltage conversion by the voltage conversion unit or the group of voltage conversion units that corresponds to the abnormality identification information without subjecting it to soft start control, and subjects any non-corresponding voltage conversion units that do not correspond to the abnormality identification information to soft start control, when the operation of the multiphase conversion unit is started, and the abnormality identifying unit identifies whether or not the non-corresponding voltage conversion units generate an abnormal current or an abnormal voltage, based on a result of detection by the detection unit during the time period in which the non-corresponding voltage conversion units are subjected to the soft start control.
