A backup power supply system (1) is designed to supply power from a first power storage device (5) to a plurality of loads (3) when a power supply (2) has caused a failure. The plurality of loads 3 includes a first load 31 and a second load 32. A first load 31 is connected to the first power supply line 41. The backup power supply system (1) is provided with a backflow prevention switch (9) which is provided on the first power supply line (41) between the first load (31) and the second load (32), and which causes the first power supply line (41) to be conductive or non-conductive by turning on and off the first power supply line (41). The backflow prevention switch 9 includes an internal diode 9D having an anode connected to one side including the first load 31 and a cathode connected to the other side including the second load 32.
一种备用电源系统1被设计为:当电源2已经引起故障时,从第一蓄电设备5向多个负载3供应电力。多个负载3包括第一负载31和第二负载32。第一负载31连接到第一电源线41。备用电源系统1包括防回流开关9,该防回流开关9在第一电源线41上设置在第一负载31和第二负载32之间,并且通过接通和关断而使第一电源线41导电或非导电。防回流开关9包括内部二极管9D,该内部二极管9D具有连接到包括第一负载31的一侧的阳极和连接到包括第二负载32的另一侧的阴极。
