Embodiment

[0036] Example description

[0037] In the embodiment of the present invention, multiple circuits can supply power to the load equipment independently, or jointly supply power to the load equipment. In addition, when the equipment power supply of multiple circuits is abnormal, the battery power supply can continue to supply power to the load equipment. Intermittent power supply, in which, the power supply of the equipment is to rectify and step down the AC mains power once, which reduces the conversion times from the AC mains power to the load equipment, and solves the problems of high power loss rate and fault influence range of the current uninterrupted power supply Large technical problems that waste material and human resources.

specific Embodiment

[0039] Please refer to figure 1, which is a structural schematic diagram of a UPS uninterruptible power supply solution in the prior art. First, AC mains 1 and AC mains 2 respectively output AC mains power to the UPS. During this process, the alternating current mains (AC) is converted into direct current (DC) for the first time, and then with the direct current (DC) output by the backup battery. Together, it is converted into alternating current (AC) for output for the second time; secondly, the alternating current after UPS is output to the AC power distribution cabinet; thirdly, the alternating current output from the AC power distribution cabinet needs to pass through the PSU (Power Supply Unit, IT power supply) It is rectified and decompressed and then output to the server. During this process, the alternating current (AC) is converted into direct current (DC) for the third time. Since the voltage required by the server is generally lower than the output voltage of the UP...

Abstract

The invention discloses a distributed uninterruptible power supply system. The system comprises a plurality of circuits. Two ends of each circuit are connected to alternating current commercial powerand load equipment respectively. Each circuit comprises an equipment power supply and a battery supply which are spare to each other. Each circuit uniformly bears electric energy required by the loadequipment. When one circuit in the plurality of circuits has a fault, the other circuits commonly and uniformly bear the electric energy required by the load equipment. Compared with the prior art, byusing the distributed uninterruptible power supply system, high system power supply efficiency and high system availability are possessed; and a problem that a fault influence range of a traditionalcentralized uninterruptible power supply system is wide is solved.

Description

technical field [0001] The invention relates to power supply technology, in particular to a distributed uninterruptible power supply system for powering load equipment. Background technique [0002] The data center accommodates a large number of IT equipment and IT systems. The IT system is used to transmit, accelerate, display, calculate, and store data information on the Internet network, IT equipment and other infrastructure. It plays a vital role in the Internet era, so it is important for Uninterrupted power supply for IT equipment and IT systems is particularly important. [0003] The current uninterrupted power supply for IT equipment and IT systems mainly depends on UPS (Uninterruptible Power Supply) and PSU (Power Supply Unit), please refer to figure 1 , the two mains electricity passes through the UPS, the AC power distribution cabinet, and the PSU to reach the IT equipment and the server of the IT system. After two conversions of AC / DC rectification and DC / DC st...
