Title:
BACKUP POWER SUPPLY SYSTEM, POWER SUPPLY BACKUP METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/200774
Kind Code:
A1
Abstract:
A backup power supply system 1 is equipped with a first auxiliary power supply 22, a second auxiliary power supply 3, a first switch circuit 26, and a second switch circuit 27. The first auxiliary power supply 22 and the second auxiliary power supply 3 are able to supply power to a load 5 when a main power supply 4 fails. The first switch circuit 26 conducts and interrupts current in a first power supply line L1 connecting the first auxiliary power supply 22 and the load 5. The second switch circuit 27 conducts and interrupts current in a second power supply line L2 connecting the second auxiliary power supply 3 and the load 5. The backup power supply system 1 is further provided with a forcing circuit 29 for forcibly interrupting current in one of the switching circuits, that is, the first switching circuit 26 or the second switching circuit 27.
