Abstract
A backup power supply system is designed to supply, when a power supply has caused a failure, power from a first electrical storage device to a plurality of loads. The plurality of loads includes a first load and a second load. The first load is connected to a first power supply line. The backup power supply system includes a backflow prevention switch provided between the first load and the second load on the first power supply line and making the first power supply line electrically conductive or non-conductive by turning ON and OFF. The backflow prevention switch includes an internal diode having an anode connected to one side including the first load and a cathode connected to the other side including the second load.
