Abstract

A power supply system includes: a first energy storage device that outputs electric power at a reference voltage; a first voltage converter that converts the reference voltage to a first voltage lower than the reference voltage; a second voltage converter that converts the reference voltage to a second voltage lower than both the reference voltage and the first voltage; a second energy storage device that stores the electric power converted by the second voltage converter; a third voltage converter that further converts the first voltage output from the first voltage converter to the second voltage; and a fourth voltage converter that further converts the second voltage to the first voltage on the basis of the electric power converted to the second voltage by the second voltage converter and the electric power stored in the second energy storage device.
