To supply power to a load even when a ground fault or short circuit occurs in one power supply system in a power supply redundant system in which power supply systems with different voltages coexist.SOLUTION: A power supply redundant system includes a DCDC converter in which a first battery of a first voltage is connected to a first side, a first switch provided between a second battery having a second voltage different from the first voltage and the second side of the DCDC converter, a load connected to the second battery and the second side of the DCDC converter separately, and a control unit that turns on the first switch and monitors the voltage of the second battery, turns off the first switch when the voltage of the second battery is a first threshold value or less, and operates the DCDC converter to output the second voltage from the second side.SELECTED DRAWING: Figure 1

    【課題】異なる電圧の電源システムが併存する電源冗長システムにおいて、一方の電源システムで地絡あるいは短絡が発生した場合にも負荷に電力を供給可能とする。【解決手段】第1電圧の第1バッテリと第1側が接続するDCDCコンバータと、第1電圧と異なる第2電圧の第2バッテリと前記DCDCコンバータの第2側との間に設けられた第1スイッチと、第2バッテリおよびDCDCコンバータの第2側と個別に接続し、第2電圧で動作する負荷と、第1スイッチをオンにして第2バッテリの電圧を監視し、第2バッテリの電圧が第1基準値以下になった場合に、第1スイッチをオフに切り換えるとともに、DCDCコンバータを第2側から第2電圧を出力するように動作させる制御部と、を備える電源冗長システム。【選択図】図1
