Power supply system

Abstract

The invention relates to the technical field of power electronics, and provides a power supply system. The power supply system comprises a high-voltage input power distribution cabinet, a high-low voltage conversion cabinet and a low-voltage output and control cabinet, wherein the high-low voltage conversion cabinet is internally provided with at least one high-voltage cabin and at least one low-voltage cabin, the high-low voltage conversion cabinet is further internally provided with an insulating partition plate located between the high-voltage cabin and the low-voltage cabin, the low-voltage cabin is internally provided with a low-voltage bus, and the high-voltage cabin is internally provided with a high-voltage bus; and the high-low voltage conversion cabinet is also internally provided with a plurality of power supply modules, each power supply module is in bridge connection with the high-voltage cabin and the low-voltage cabin, the power supply module comprises a high-voltage cavity, a low-voltage cavity and an isolation unit, the high-voltage cavity and the low-voltage cavity are arranged corresponding to the high-voltage cabin and the low-voltage cabin respectively and electrically connected with the high-voltage bus and the low-voltage bus respectively, and the isolation unit is connected with one end of the high-voltage cavity and one end of the low-voltage cavity. According to the invention, the input high voltage is isolated from the output low voltage and the control low voltage so as to improve the safety.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a power supply system. Background technique [0002] Datacenter, or server farm, refers to facilities used to house computer systems and related components, such as telecommunications and storage systems. Typically it includes redundant and backup power supplies, redundant data communication connections, environmental controls (eg air conditioning, fire extinguishers) and various safety equipment. [0003] At present, the amount of data is exploding rapidly, the value of data is increasing suddenly, and cloud computing is developing rapidly. In recent years, the scale of data centers has maintained a rapid growth trend. In the context of the rapid increase in power consumption of data centers, there is an urgent need to reduce power transmission losses and optimize data center power supply methods. [0004] The technical requirements for power supply in application en...
