Abstract

The embodiment of the invention provides an alternating current and direct current power supply and system. The power supply comprises: an alternating current and direct current conversion device with a first direct current confluence busbar; a direct-current switch array comprising a plurality of direct-current switches and a plurality of first fuses corresponding to the direct-current switches, wherein the direct-current switches are all connected to the first direct-current confluence busbar, and each first fuse is correspondingly connected to the corresponding direct-current switch; a plurality of DC / DC converters corresponding to the plurality of first fuses, wherein each DC / DC converter is connected to one of the first fuses; and a second DC confluence busbar, wherein the output ends of the plurality of DC / DC converters are connected in parallel and then are connected to the second DC confluence busbar. According to the invention, when the DC / DC converters break down, normal power supply to the load is not affected, or when the load changes, is overhauled or is stopped, the DC / DC converters can be disconnected or restarted on line.

Description

technical field [0001] The embodiments of the present application relate to the technical field of power supplies, and in particular to an AC and DC power supply and a system. Background technique [0002] Large and medium-sized data centers, as the core infrastructure of information construction in various industries such as communication operators, banking services, and large commercial group companies, carry important tasks such as storage, transmission, exchange, management, and processing of massive data. The continuity and stability of its normal operation. For example, if there is an abnormal power supply interruption even for only 1 second, the services carried by IT equipment may be interrupted for several hours. After a power outage, IT equipment needs to be restarted, check for hardware failures, check for data loss, and reload services. A series of actions will take at least several hours. Therefore, the reliability of the power supply and distribution system o...
