Abstract

The invention discloses a multi-source energy storage DC power supply device and UPS equipment. The backup power supply of the UPS equipment in this application includes batteries and supercapacitors. Considering that the cycle life of supercapacitors is much higher than that of batteries, this application gives priority to using supercapacitors to supply power to the DC bus when the mains power is interrupted. When the battery is powered on, the DC bus is powered by the battery, so the application reduces the utilization rate of the battery to a certain extent and prolongs the service life of the battery; The power supply can also provide a certain backup time for the system to save important data to prevent loss of important data, thereby improving the overall backup capability of the backup power supply.

Description

technical field [0001] The invention relates to the field of UPS backup power supply, in particular to a multi-source energy storage DC power supply device and UPS equipment. Background technique [0002] UPS (Uninterruptible Power Supply, uninterruptible power supply) equipment is widely used in large wind power master control and converter systems to provide stable and uninterrupted power supply for the loads in the system. At present, the working principle of UPS equipment is: when the mains power is normal, the UPS equipment rectifies the mains power into direct current through the AC / DC converter, and then inverts the direct current into alternating current through the DC / AC converter to supply the system load (rectification The purpose of the inverter is to stabilize the mains voltage); when the mains is interrupted, the UPS equipment immediately connects the DC power stored in its own backup power supply to the DC bus in the equipment (that is, the DC bus between the ...
