Abstract
A load circuit operates by power supplied from a power supply apparatus. A capacitive element is connected in parallel with the load circuit. A switching element is connected between the power supply apparatus and the load circuit in series with the power supply apparatus and the load circuit. A monitor section monitors voltage of the capacitive element and is connected in parallel with the capacitive element. An inrush current control section changes resistance of the switching element on the basis of the voltage monitored by the monitor section in order to control inrush current that flows at the time of an electronic device being plugged into or unplugged from the power supply apparatus. A breaker circuit prevents electric charges stored by the capacitive element from flowing into the monitor section at the time of the electronic device being unplugged from the power supply apparatus.
