Title:
REDUNDANT POWER SUPPLY DEVICE AND SYSTEM, UNINTERRUPTIBLE POWER SUPPLY EQUIPMENT, SWITCH, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/050812
Kind Code:
A1
Abstract:
Embodiments of the present application provide a redundant power supply device and system, uninterruptible power supply equipment, a switch, and a control method. The device comprises two sets of uninterruptible power supply equipment, wherein each set of uninterruptible power supply equipment comprises a main circuit and a bypass circuit which are mutually independent. Output ends of the two main circuits of the two sets of uninterruptible power supply equipment serve as two first outputs. Output ends of the two bypass circuits of the two sets of uninterruptible power supply equipment are connected in parallel to serve as a second output. At least one bypass circuit in the two bypass circuits is in an on-state. Every two of the second output and the two first outputs can be combined to supply power to a load in a redundant mode. Compared with the existing power supply mode in which two main circuits are used for supplying power to a load, in the present embodiment, two main circuits and at least one bypass circuit can be used for supplying power to a load; the bypass circuit for bearing the load is added, so that the UPS capacity can be reduced, the utilization rate of equipment is improved, and the cost is reduced.
