　　Current status of UPS power supply technology and characteristics of UPS uninterruptible power supply. In recent years, with the continuous improvement of UPS power supply performance requirements, new branches of UPS power supply technology have emerged. Among them, UPS power network intelligent technology and full digital technology are new UPS power supply technologies.

　　Current status of UPS power technology

　　At present, the UPS power supply market has matured. The concept of using UPS to improve the availability of power supply systems has been deeply rooted in the hearts of the people and is widely accepted. Users have paid enough attention to the importance of improving power supply quality with the help of UPS power supply system.

　　(1) Safety and reliability. Failures in the power supply system are inevitable but can be reduced. Safety and reliability are still the main aspects that need to be solved urgently in the current UPS power supply system.

　　(2) Changes in measurement standards. UPSs of various models and specifications currently on the market can basically meet the requirements for power supply to the load. The various output electrical performance indicators of UPS are no longer factors affecting the normal operation of the load and the main criterion for measuring performance when purchasing.

　　(3) Treat both the symptoms and the root causes. According to statistics, more than half of the total number of system failures are caused by human operations, installation problems and quality problems in other links and equipment in the power distribution system, or UPS failures are induced by these reasons. Therefore, we must consider improving equipment quality and technology while also focusing on professional training of supporting technicians. The lack of professional UPS power maintenance personnel is also one of the important reasons for UPS power failure.

　　Simply improving the reliability of UPS power supply equipment cannot fundamentally solve the safety and reliability of the entire power supply system, and it cannot even ultimately form an uninterrupted power supply system.

　　(4) Failure repair is slow. After a power supply system failure occurs, the system failure cannot be repaired in a timely manner due to the complexity of the system, the response speed of the product supplier, the technical level and work experience of the maintenance personnel, the reserve and supply of spare parts, and the search and analysis of the cause of the failure. , and even the real cause of the failure cannot be found.

　　Characteristics of UPS uninterruptible power supply

　　Energy conservation and environmental protection have become the guiding principles for UPS manufacturers to carry out product technology innovation. For UPS, the input power factor indicates its ability to absorb the active power of the grid and the extent of its impact on the grid. Reducing the input harmonics of the power supply can not only improve the load characteristics of the UPS on the power grid, reduce serious pollution to the power grid, but also reduce harmonic interference to other network equipment.

　　①After being connected to work, the UPS can provide stable and reliable AC power without noise and interference to the electrical load.

　　②Usually the UPS power supply is in an online working state, obtaining electric energy from the main power supply as load input, and isolating the surge and electronic interference of the power line from the load.

　　③In the online state, the UPS power supply ensures the stability of the load input voltage by compensating the voltage fluctuation of the main power supply. Utilizes transformer tap transitions to provide voltage regulation for maximum operating efficiency.

　　④During the tap jump process, the load temporarily switches to battery power supply to ensure the continuity of load power supply.

　　⑤When the online voltage is abnormal or there is a power outage, the UPS power supply will be powered by the battery and output a pure sine wave AC voltage. And it is uninterrupted at any time within the rated load range.

　　Summary: With the continuous updating and development of science and technology, UPS power supply technology has also made great progress, and UPS power supply technology has good development prospects and rapid development speed. In order to comply with the development and trends of modernization, UPS power supply technology must continuously innovate and optimize its own technology while meeting people's needs to ensure that it has certain advantages in the development process.
