Uninterruptible power supply Features Working principle of uninterruptible power supply

Due to the development of information technology, the network has become an indispensable part of people's life and work, the reliability of the power supply of the digital computer room that constitutes the network has become the key, and the reliable power supply of the computer room is the most important, usually uninterruptible power supply is used to maintain the uninterrupted operation of key commercial equipment or precision instruments such as computers (especially servers) or switches. To prevent computer data loss, telephone communication network interruption or instrument loss of control, today we will take a look at the relevant content of uninterruptible power supply. Uninterruptible power supply is a device that continuously provides backup AC power for electrical load equipment and maintains the normal operation of electrical equipment in the case of abnormal power grid (such as power failure, undervoltage, interference or surge current).

1, green, energy saving, environmental protection: in the world energy pattern changes, international oil prices violent shocks, the global energy supply of the situation, energy saving and environmental protection has become the guiding principle of UPS manufacturers for product technology innovation. For UPS, the input power factor indicates its ability to absorb the active power of the grid and the degree of impact on the grid. Reducing the input harmonics of the power supply can not only improve the load characteristics of the UPS to the power grid, reduce the serious pollution to the power grid, but also reduce the harmonic interference to other network equipment. Many UPS manufacturers have introduced products with a power factor close to 1, which can minimize reactive power consumption.

2, high-frequency: compared with the traditional power frequency UPS, high-frequency UPS uses power factor correction and high-frequency soft switching technology, eliminating the power frequency conversion link, so the operation efficiency is higher, the harmonic pollution of the grid and reactive power consumption is minimal, fully able to meet the relevant domestic and foreign power industry standards. In addition, the high-frequency power conversion device has significant effects in reducing the volume and weight of magnetic components, reducing manufacturing costs, curbing operation noise, energy saving and environmental protection, so it is more and more recognized by users.

3, high-power, modular: due to the rapid development of the IT industry, the amount of data in the data center is also continuing to grow at an explosive rate, followed by increased power consumption. On the one hand, UPS is developing in the direction of more power, and on the other hand, in response to the demand for the phased expansion of uninterruptible power supply capacity, product modularization has been an irresistible trend. More personalized user needs, larger data center scale and higher maintenance costs make UPS is no longer a simple uninterrupted power supply equipment, a full set of power supply and management solutions for different industries will be favored by the market.
