摘要： PROBLEM TO BE SOLVED: To provide a power supply system capable of suppressing electric power loss and deterioration of each power supply device while attaining excellent stability in executing power supply using a plurality of power supply devices.
SOLUTION: A switching element, which corresponds to the power supply device having a higher inter-terminal voltage of two power supply devices 1A, 1B, is selectively turned on. Then, the switching element corresponding to the power supply device having a lower inter-terminal voltage is turned off. This prevents a particular power supply device from being overloaded and also prevents a current flow between different power supply devices 1A, 1B without causing any unnecessary power loss. Furthermore, the power of the power supply device having higher inter-terminal voltage is selectively output, so that fluctuations between respective power supply devices 1A, 1B are allowed to some extent.
