Computer built-in uninterruptible power supply emergency system

Abstract

The invention discloses a computer built-in uninterruptible power supply emergency system which comprises an electric supply rectification unit, a switch voltage transformation unit and more than two output rectification filtering unit sets. Output rectification filtering units are divided into positive voltage output rectification filtering units and a negative voltage output rectification filtering units. The electric supply rectification unit is connected with the switch voltage transformation unit which is connected with the output rectification filtering units. The computer built-in uninterruptible power supply emergency system is characterized in that the output end of the electric supply rectification unit is connected with an outage detecting unit, one positive voltage output rectification filtering unit set is connected with an energy storage unit which is connected with a control distribution unit, and the outage detecting unit is connected with the control distribution unit which is connected with a shutdown determining unit. The computer built-in uninterruptible power supply emergency system is low in power and cost so that the emergency system can be accepted by the masses, and computers cannot be damaged by outage any longer.

Description

technical field [0001] The invention relates to an uninterruptible power supply, in particular to a built-in computer uninterruptible power supply emergency system. Background technique [0002] With the development of society and the advancement of science and technology, computers have become popular in all fields of life and have become an indispensable tool for people. At present, the work of computers is completely dependent on electricity. In some places where computers are required to work uninterruptedly, in order to avoid unexpected power outages, an external inverter is equipped as an uninterruptible power supply. The inverter mainly stores electricity through the battery at ordinary times. Then the direct current of the battery is converted into mains power to provide temporary emergency power for the computer in time to avoid file loss and hardware damage caused by unexpected shutdown. However, the inverter is not widely used as an uninterruptible power supply. ...

Problems solved by technology

However, the inverter is not widely used as an uninterruptible power supply. It is mainly used in some key industries, such as banks and communication base stations, and has not yet entered the homes of ordinary people. With the increasingly powerful functions of the computer, the power of the computer is getting larger and larger, which requires the power of the inverter to increase to meet this change, and further increase the cost price; there is also power loss in the inverter process, The conversion of computer switching power supply to direct current also requires power loss. In order to meet the actual power demand of the computer, the power of the inverter must be made larger, which is not conducive to the reduction of power and cost of the inverter; and the current solution Under the frame structure, the actual power of the computer does not change before and after the mains power failure, and the inverter has to undertake the power supply for the entire system of the original computer, which is not conducive to reducing the power and cost of the inverter; the above factors all restrict It enters the home and ordinary office space, and the sales volume of computers in these fields is huge in our country, and every computer user has experienced sudden power outages, especially in areas with unstable power supply during peak power consumption, which will not only cause file corruption Loss, more serious damage to the hardware, especially the hard disk, frequent sudden power outages will damage the disk and cause bad sectors, serious scrapping will result in loss of stored information, and shortened component life will also cause huge waste. In line with the current development requirements of environmental protection and conservation, the application coverage of the existing uninterruptible power supply architecture based on inverter UPS is too small, and it still needs to provide better technical solutions for technological innovation to make up for it.
