Abstract
A power supply system (101) includes a first power supply apparatus (111a) and a second power supply apparatus (111b) connected to a load in parallel, for supplying power to the load (115). The first supply apparatus (111a) includes a first controller that controls the output voltage of the first supply apparatus (111a) when a power supply from the first supply apparatus (111a) to the load 115 is equal to or greater than a power requirement by the load (115), and controls the output current of the first supply apparatus (111a) when the supplied power is less than the required power. The second power supply apparatus 111b includes a second controller that stops the second supply apparatus from supplying power (111b) when the power supply is equal to or greater than the power requirement, and controls the output voltage of the power supply apparatus (111b) when the power supply is less than the power requirement.
