To provide a mobile power supply system with a simple configuration and increased redundancy.SOLUTION: A mobile power supply system includes normal power supplies 21, 22, a normal current path 11 connected to the normal power supply, redundant power supply 41r which is a power supply different from the normal power supply, and a redundant current path 31r connected to the redundant power supply. The mobile power supply system includes: first current path 31a connected to first redundant loads 41a, 41b; and a second current path 32a provided with the first current path in parallel and connected to second redundant loads 42a, 42b. The mobile power supply system includes includes: a path switch 30 having a first normal switch 36m and a second normal switch 37m; and a control unit for controlling the path switch. The normal power supply can be connected to the normal load and can be connected to at least one of the first redundant load and the second redundant load. Therefore, it is possible to obtain the mobile power supply system with a simple configuration and enhanced redundancy.SELECTED DRAWING: Figure 1 【課題】簡素な構成で冗長性を高めた移動体用電源システムを提供する。【解決手段】移動体用電源システムは、通常電源２１、２２と、通常電源と接続している通常電流経路１１と、通常電源とは異なる電源である冗長電源４１ｒと、冗長電源と接続している冗長電流経路３１ｒとを備えている。移動体用電源システムは、第１冗長負荷４１ａ、４１ｂと接続している第１電流経路３１ａと、第１電流経路に並列に設けられ、第２冗長負荷４２ａ、４２ｂと接続している第２電流経路３２ａとを備えている。移動体用電源システムは、第１通常スイッチ３６ｍと、第２通常スイッチ３７ｍとを有する経路スイッチ３０と、経路スイッチを制御する制御部とを備えている。通常電源は、通常負荷と接続するとともに、第１冗長負荷と第２冗長負荷との少なくとも一方に接続可能である。このため、簡素な構成で冗長性を高めた移動体用電源システムを得ることができる。【選択図】図１
