Abstract

A power supply device comprises a first boost converter configured to transmit electric power with conversion of a voltage between an electric load side and a power storage device side; a second boost converter connected in parallel to the first boost converter relative to an electric load and configured to transmit electric power with conversion of a voltage between the electric load side and the power storage side; and a control device configured to control the first boost converter and the second boost converter. At a predetermined time, the control device performs a loop current control that controls the first boost converter and the second boost converter such that a loop current flows in a closed circuit including the first boost converter and the second boost converter.
