Abstract

A drive device comprises a plurality of boost converters connected in parallel to each other and placed between a power storage device side and an electric load side; a drive mode setting switch operated to set a drive mode among a plurality of drive modes; and a control device configured to control the plurality of boost converters by employing one control mode including a first control mode that drives and controls only some boost converters out of the plurality of boost converters and a second control mode that drives and controls a larger number of boost converters than some boost converters. The control device changes a switchover reference value that is used to switch over control between the first control mode and the second control mode according to the magnitude of an electric load, based on a drive mode set by operation of the drive mode setting switch.
