Title:
BACKUP POWER SUPPLY SYSTEM CONTROL METHOD AND BACKUP POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/089980
Kind Code:
A1
Abstract:
The input port of this backup power supply system is connected to a power supply, and the output port thereof is connected to a load. A power supply path connects the input port and the output port to each other. A first voltage conversion unit is connected between the power supply path and an electricity storage unit. A second voltage conversion unit has a first end connected to the power supply path and a second end connected to the output port. A reverse flow prevention unit is connected between the input port and the output port and prevents current from flowing from the second end of the second voltage conversion unit to the input port. The first end of a first capacitor is connected between the node to which the first voltage conversion unit and the second voltage conversion unit are connected and the input port, and the second end of the first capacitor is connected to the ground.
