Problems solved by technology

[0004] However, if the UPS system wants to output a stable circuit, it must keep the AC phase, phase sequence, and frequency consistent. If it is inconsistent, it will cause grid disorder, but if it is necessary to maintain the AC phase, phase sequence, and frequency, it will inevitably cause the UPS Difficulty in system expansion

Abstract

The invention discloses a high-voltage direct current power supply system which comprises first rectification equipment, second rectification equipment, a two-way direct current power module, a power module and a direct current generatrix. According to the technical scheme, a direct current generatrix power supply mode is adopted, the output current of the power module is directly supplied to the direct current generatrix through the two-way direct current power supply module, and the direct current voltage of the direct current generatrix is kept unchanged, so that load equipment connected to the direct current generatrix can run safely and reliably; the problems of phases and phase sequences are solved, a hot plugging mode is adopted, new load equipment can be merged into the direct current generatrix to work by only reserving a rack position, and convenience is brought to capacity expansion and maintenance.

Description

technical field [0001] The present application relates to the technical field of power supply systems, and more specifically, to a high-voltage direct current power supply system. Background technique [0002] With the rapid development of information technology and data services, especially the rapid development of IDC (Internet Data Center, Internet Data Center) data center business, IDC data center equipment has higher and higher requirements for power supply security and reliability. [0003] In the prior art, the IDC data room generally uses a UPS system (Uninterruptible Power System / Uninterruptible Power Supply, uninterruptible power supply system) to supply power to the IDC data room equipment. In the UPS system power supply system, when the city power is normal, the DC main circuit has a DC voltage, which is supplied to the DC-AC AC inverter to output a stable AC voltage. At the same time, the city power is rectified to charge the battery. In case of sudden power fa...
