Title:
BUS VOLTAGE CONTROL METHOD AND SYSTEM FOR UNINTERRUPTIBLE POWER SUPPLY SYSTEM, AND RELATED COMPONENT
Document Type and Number:
WIPO Patent Application WO/2023/000297
Kind Code:
A1
Abstract:
A bus voltage control method and system for an uninterruptible power supply system, and a related component, comprising: detecting a main circuit input voltage; determining a current bus voltage target value on the basis of the main circuit input voltage; and controlling bus voltage target values of uninterruptible power supplies connected in parallel in the uninterruptible power supply system to be the currently determined bus voltage target value, wherein the uninterruptible power supply system at least comprises two uninterruptible power supplies connected in parallel. By means of the solution of the present application, good dynamic response and overall efficiency can be ensured, and a situation that a direct current bus voltage rises due to uncontrollability is avoided.
