PROBLEM TO BE SOLVED: To cope with both a short-circuit failure and an open-circuit failure and to secure power feeding to a load in either of two power supplies for giving redundancy to power feeding to the load.SOLUTION: A power supply box 4 includes a switch 431, a switch 432, and a control circuit 41. The switch 431 has one end connected to a battery 1, and the other end connected to a load 3, and is turned on during normal operation. The switch 432 has one end connected to a battery 2, and the other end connected to the load 3, and is turned on during normal operation. The control circuit 41 turns off the switch 431 in the case that current I1 flowing to the switch 431 is caused to flow in an opposite direction from the current I1 caused to flow during normal operation or that the current is smaller than a prescribed threshold.SELECTED DRAWING: Figure 1

    【課題】負荷への給電に冗長性を与える二つの電源のいずれか一方において、短絡故障、開放故障のいずれに対しても対応し、負荷への給電を確保する。【解決手段】電源ボックス4は、スイッチ431と、スイッチ432と、制御回路41とを備える。スイッチ431は、バッテリ1に接続される一端と、負荷3に接続される他端とを有し、正常動作時においてオンする。スイッチ432は、バッテリ2に接続される一端と、負荷3に接続される他端とを有し、正常動作時においてオンする。制御回路41は、スイッチ431に流れる電流I1が、正常動作時において流れる電流I1と反対向きに流れる場合、もしくは所定閾値よりも小さい場合、スイッチ431をオフさせる。【選択図】図1
