To provide a power supply redundant system capable of performing an appropriate protection as well as realizing a miniaturization.SOLUTION: A power supply redundant system comprises: a main battery B1 that can supply a power to a first load part LO1 and a second load part LO2; a sub battery B2 that can supply a power to at least the second load part LO2; a first switching part SW1 that switches a power supply path reached from the main battery B1 and the sub battery B2 to the first load part LO1 and the second load part LO2; a control substrate 30 that mounts a switching control part that switches and controls the first switching part SW1; and a housing that houses at least the main battery B1, the sub battery B2, and the first switching part SW1. The control substrate 30 receives the supply of the power from both of the main battery B1 and the sub battery B2 to be operated.SELECTED DRAWING: Figure 1

    【課題】小型化を図ると共により適切な保護を図ることが可能な電源冗長システムを提供する。【解決手段】第1負荷部LO1及び第2負荷部LO2に電力供給可能なメインバッテリB1と、少なくとも第2負荷部LO2に電力供給可能なサブバッテリB2と、メインバッテリB1及びサブバッテリB2から第1負荷部LO1及び第2負荷部LO2に至る電力供給経路を切り替える第1切替部SW1と、第1切替部SW1を切替制御する切替制御部を搭載した制御基板30と、少なくともメインバッテリB1、サブバッテリB2、及び、第1切替部SW1を収納する筐体と、を備え、制御基板30は、メインバッテリB1及びサブバッテリB2の双方から電力供給を受けて動作可能となっている。【選択図】図1
