Zusammenfassung:A power supply system for supplying a plurality of power-supply voltages to a load. The power supply system includes: a plurality of voltage output units which output the plurality of power-supply voltages; a gradient calculation unit which calculates the gradients of the plurality of power-supply voltages in intervals subsequent to certain moments immediately after the beginnings of rises of the plurality of power-supply voltages on the basis of the levels of the plurality of power-supply voltages at the moments; a gradient extraction unit which extracts the gentlest one of the gradients; and a power-supply control unit which controls the plurality of voltage output units so that the plurality of power-supply voltages rise with the gentlest one of the gradients.
