3.2v 60ah lifepo4 battery.The truth about the eight major technological development trends of UPS power supply is disclosed

　　1. Intelligent UPS power supply

　　Through the analysis and synthesis of various types of information, the intelligent system should not only complete the control function of the normal operation of the corresponding parts of the UPS, but also complete the real-time monitoring of the running UPS, analyze and process the important data information in the circuit, and draw various conclusions from it. Whether some circuits are working normally and other functions; when the UPS fails, it can conduct timely analysis based on the test results, diagnose the fault location, and provide treatment methods; take necessary emergency protection control actions according to the needs of the site in a timely manner to prevent failures Expansion of influence; complete necessary self-maintenance, have the function of exchanging information, and can input information to the computer or obtain information from the networked machine at any time.

　　2. UPS power digitalization

　　UPS uses the latest digital signal controller (DSP) and digitized Hall sensor devices to achieve 100% digital operation of the UPS system. A multiple microprocessor redundant system is also used, using multiple microprocessors with independent power supplies to control the rectifier, inverter and internal static bypass, thereby improving the digitalization and reliability of the system.

　　3. High-frequency UPS power supply

　　The power switch of the first generation UPS is a thyristor, the second generation is a high-power transistor or field effect transistor, and the third generation is an IGBT (insulated gate bipolar transistor). The switching speed of high-power transistors or field-effect transistors is an order of magnitude higher than that of thyristors, and the current capacity and speed of IGBT power devices are much larger and faster than that of high-power transistors or field-effect transistors, which reduces the operating frequency of the power conversion circuit. up to 50kHz. The increase in the frequency of the conversion circuit greatly reduces the inductance, capacitance, noise, and volume used for filtering, and greatly improves UPS efficiency, dynamic response characteristics, and control accuracy.

　　4. UPS power supply redundant parallel technology

　　Through the development of new application technology, multi-module redundant parallel operation in the UPS can be realized without the need for additional central control components. The load is evenly distributed. When a problem occurs in a certain module, the load is automatically transferred and hot-swappable for maintenance. , greatly improving the power supply reliability of a single UPS. In addition, the system composed of multiple UPS operates redundantly. If a single UPS fails, it will be shut down immediately, and other UPS systems will automatically bear the entire load without any impact on the load.

　　5. UPS power supply integration

　　With the development of informatization, the application fields of power supply protection continue to expand and the requirements continue to increase. It is difficult for UPS to meet these needs alone. It must control the links involved in the entire power system. UPS starts from the initial equipment protection and system protection. Pure backup power technology has developed into today's integrated applications of information protection, intelligent management and overall computer room integration, and its connotation has expanded to power generation, power distribution, conversion, uninterruptible power supplies, computer rooms, power equipment, power cables, data cabling, and environmental monitoring. And system management, etc., it is no longer UPS in the original sense. UPS equipment is only the core component of the system.

　　6. The development trend of customer integration demand will be further strengthened

　　With the advancement of science and technology, users are no longer satisfied with the power guarantee function of a single UPS, and have begun to care about the reliability and availability of the entire power supply system, the physical infrastructure that supports the entire data center, and its operational efficiency. The integrated demand of downstream customers for the products and services of UPS manufacturers will guide equipment providers to provide corresponding solutions. The major UPS manufacturers in the future will no longer be just a single UPS supplier, but will become a provider of overall solutions for power quality.

　　7. Green UPS power supply

　　The harmonic currents generated by various electrical equipment and power supply devices seriously pollute the power grid. With the introduction of various policies and regulations, the call for pollution-free green power supply devices is getting louder and louder. In addition to installing a high-efficiency input filter, the UPS should also adopt power factor correction technology at the input end of the power grid, which can not only eliminate the harmonic current generated by the rectifier and filter circuit itself, but also compensate for the input power factor. The rectifier uses IGBT technology, which can increase the input power factor to close to 1, and the pollution to the power grid has been reduced to the level of a resistive load.

　　8. UPS power network

　　In the Internet age, there is also a need for "network UPS", which has larger power storage, can serve multiple computers or other peripherals at the same time, and can achieve dynamic configuration between loads through some mechanism.

　　In recent years, the country and industry have increased investment in the UPS power supply market. Both at the technical level and at the product level, the UPS power supply market has undergone great improvement and development. The accelerated pace of informatization construction in application fields will inevitably drive greater market demand for UPS uninterruptible power supplies.

　　Integration With the development of informatization, the application fields of power protection are constantly expanding and the requirements are constantly improving. Energy storage electrical UPS products are widely used in: communications, electric power, public security, finance, network, medical care, security, industrial automation, rail transit, In aerospace and navigation and other fields, lithium battery UPS has been widely used in various fields. Let me give a few examples:

　　Vehicle-mounted UPS application - aircraft control vehicle of the Ministry of Aerospace

　　Communication base station application——China Mobile

　　Transportation Application—Shanghai-Chengdu Expressway

　　Industrial field application——Baosteel Group

　　Data center - school computer room power supply

　　With the performance of UPS power equipment and the application advantages in corresponding fields, lithium battery UPS power technology will continue to expand in the future, and the UPS market demand will continue to increase in the future. Let us wait and see.
