Zusammenfassung:	A power supply system that can control a power according to a dynamic characteristic of a power source is provided. In a power supply system that supplies a power to a load from multiple power supplies connected in parallel, each of the power supplies includes a power supply and a power supply circuit, and the power supply circuit includes a drooping characteristic calculation unit that calculates a voltage command value to cause an output voltage output by the power supply to droop at a predetermined drooping rate with respect to the output power, and a ramp rate control unit that corrects the voltage command value to reduce an amount of change of the output voltage when the amount of change of the output power per unit time exceeds a predetermined ramp rate, and a ramp rate different according to the type of the power source is set for each of the power supplies.
