摘要：
Each of the power supply units (20) in a power supply apparatus includes a voltage conversion circuit (21) that converts input voltage into output voltage within a predetermined voltage range an output capacitor (22) that outputs supply power while accumulating charges according to the voltage converted by the voltage conversion circuit (21), and an overload detection circuit (23) that detects an overload of the output capacitor (22) and when the overload is detected, notifies an apparatus (3) operated using the power supplied from the power supply apparatus of an overload signal requesting a suppression of power consumption.
