Abstract
A power supply unit includes an electronic control unit that executes; a first control for controlling first and second converters such that a voltage of the load power line becomes a predetermined voltage by driving the first converter in a state where the second converter is stopped, and a second control for controlling the first and second converters such that the voltage of the load power line becomes the predetermined voltage by driving the second converter in a state where the first converter is stopped. The electronic control unit is configured to, when shifting from first to second control, control the first and second converters such that the voltage of the load power line becomes the predetermined voltage by driving the second converter, and stop the first converter after an output current of the first converter has become less than a predetermined current.
