Alternating current/direct current power supply conversion control system

Abstract

The invention belongs to the field of mobile communication devices, and particularly relates to an alternating current / direct current power supply conversion control system used for supplying power to repeaters, which comprises a shell, wherein the shell contains an alternating current / direct current power supply conversion module which is connected in the power supply circuit of a terminal device in series; the port of the alternating current / direct current power supply conversion module is connected with the port of a storage battery; the alternating current / direct current power supply conversion module comprises an anti-jamming part, a rectification conditioning part, a flyback converter, a push-pull converter and a detection control part; one output port of the anti-jamming part is connected with the input port of the terminal device via the rectification conditioning part; the other output port of the anti-jamming part is connected with the port of the storage battery via the rectification conditioning part and the flyback converter; one port of the detection control part is connected with the output port of the anti-jamming port; the other port is connected with the output port of the push-pull converter; and the output end of the detection control part is connected with the input port of the terminal device. The invention has the advantages of low cost, favorable compatibility, convenient engineering installation, low maintenance cost and high stability.

Description

Technical field [0001] The invention belongs to the field of mobile communication equipment, and particularly relates to an AC / DC power conversion control system for power supply of a repeater. Background technique [0002] With the rapid development of mobile communication technology today, communication base stations and repeaters have been spread all over the country, and enough communication base stations and repeater coverage systems can meet people's daily mobile communication needs. However, in rural areas, tourist areas, suburbs and other remote areas, the lack of city power supply and the prone to failure of the power supply grid have existed for a long time, often causing mobile communication equipment to fail to work properly, resulting in terminal users being unable to use mobile phones to talk, affecting daily life and work problem. [0003] In response to the above problems, communication operators usually have the following solutions: [0004] (1) Purchasing solar ba...

Problems solved by technology

Remote power supply systems are usually installed in suburbs, towns, and scenic tourist areas. For its basic components, see image 3 As shown, the near-end machine of the remote power supply system is installed in the base station computer room, and the output voltage of the DC-48V power cabinet of the base station is boosted to 380V DC voltage through the remote power supply system to provide power input for the remote machine of the remote power supply system; its disadvantages It is a large amount of engineering and a lot of initial investment. The installation of terminal equipment is greatly affected by installation distance, environment, and terrain factors. It is difficult to lay supporting cables and optical cables.
