What are the working principles of UPS power lithium batteries

The lithium battery UPS power supply is generally composed of a rectifier, a power battery, an inverter, a static switch and a control system. The online UPS power supply is usually used. The UPS power battery first converts the AC power input from the mains into a regulated DC power supply, supplies the lithium battery and the inverter, and then becomes a stable, pure, and high-quality AC power supply through the inverter. It can completely eliminate any power problems that may occur in the input power supply, such as voltage fluctuations, frequency fluctuations, harmonic distortion, and so on. Lithium battery UPS power supply is a constant voltage and constant frequency uninterruptible power supply with an energy storage device and an inverter as an important component. When the mains power is normal, the UPS power supply will stabilize the mains power or stabilize the frequency for the load to use, and at the same time charge the battery in the machine; when the mains power is interrupted, the UPS will immediately within 4-10 milliseconds or within zero interruption time The power of the lithium battery is continuously supplied to the load through inverter conversion, so that the load can maintain normal work, so as to save data and protect the software and hardware of the load from damage. In principle, the UPS power battery is a kind of power electronic equipment that integrates digital and analog circuits, automatically controls the inverter and maintenance-free energy storage devices; from the functional point of view, the lithium battery UPS can be used when the mains is abnormal. , It can effectively purify the city power; you can also continue to supply power to computers and other equipment at a time when the city power is suddenly interrupted, so that you can have ample time to deal with it; from the perspective of use, with the advent of the information society, UPS power supplies are widely used Land use is used in all links from information collection, transmission, resolution, storage to use, and its importance is added with the increasing importance of information use.
