ABSTRACT:
A multi-phase voltage converting device includes voltage converters each performing voltage conversion based on a control period selected from among a plurality of predetermined control periods, and a control device indicating the control period to the voltage converters. The control device updates the control period of voltage converters in a predetermined period related commonly to the plurality of control periods. The update period is a least common multiple of the plurality of control periods. The plurality of voltage converters are n in number, and the control device successively updates the control periods for the plurality of voltage converters with a time difference equal to 1
of the update period. Thereby, the multi-phase voltage converting device suppressing output voltage ripples can be provided.
