Patent ID: 8798826

Claim:
A power supply system capable of supplying/receiving electric power to/from a load device, comprising: a power line for supplying/receiving the electric power between the power supply system and said load device; a plurality of power storage devices that are chargeable/dischargeable; a plurality of converters corresponding to said plurality of power storage devices, and each configured to be capable of performing voltage conversion between the corresponding power storage device and said power line; a target voltage setting unit for setting a target voltage of said power line; and a voltage control unit for controlling a voltage of said power line to be said target voltage by controlling at least one of said plurality of converters, wherein: when said target voltage is lower than a target voltage lower limit value that is set higher than a maximum one of voltages of said plurality of power storage devices, said target voltage setting unit setting said target voltage lower limit value as said target voltage, and said target voltage lower limit value is set to a voltage that is not affected by a dead time to prevent a short circuit in upper and lower arms of said plurality of converters.
