Discussion on portable UPS technology and analysis of UPS research status at home and abroad. Portable UPS is specially designed for outdoor emergencies. The product is small in size, light in weight, high in capacity and high in power. It has integrated AC and DC output and is easy to carry, providing reliable power supply guarantee for various emergency scenarios. Today, the editor will share with you the portable UPS technology and UPS research status at home and abroad.
1. Discussion on key technologies of portable UPS
1. Parallel technology
In some situations, portable UPS must be connected in parallel to achieve the required capacity. The core of parallel technology is the current sharing problem of each parallel part. The parallel connection of UPS is much more complicated than the general parallel connection of DC power supply. It must meet the following three conditions :
The amplitude of the output voltage of each inverter must be equal;
The phase of the inverter's output voltage must be consistent. Parallel connection technology can be used to form a redundant power supply system with fault tolerance.
2. Inverter technology
The inverter is the core of the entire portable UPS. In order to improve the performance of the entire UPS, more research is focused on UPS inverter control technology. For the circuit structure of the portable UPS inverter, there are mainly the following:
(1) Inverter of power frequency machine
The advantage of this inverter structure is that it provides users with a truly isolated power supply, has harmonic suppression, and can improve the overload capacity of single-phase loads; the disadvantage is that the output three-phase voltages are coupled to each other and cannot be independently controlled and the device is large in size.
(2) Inverter of high frequency machine
The advantage of the high-frequency inverter is that the output voltage can be controlled independently and the device is small in size; its disadvantage is that the input and output are not isolated, resulting in poor reliability and safety, and the output voltage has a certain DC component.
(3) New online interactive technology
This kind of inverter has the advantages and disadvantages of high frequency inverter.
(4) Four-arm conversion technology
This technology is under research. It can independently control the output three-phase voltage, but its control model moves within a polyhedron and the algorithm is complex.
3. Rectification technology
In recent years, portable UPS has adopted high-frequency rectification technology using IGBT. Since these circuit structures can continuously use various new digital control methods, its power factor can reach more than 0.99 and the harmonic current is less than 3%. It is a real Green power supply has become a hot topic of research in recent years. The hot spots of rectification technology are mainly focused on two solutions: voltage-type three-phase rectification technology and current-type three-phase rectification technology.
2. Research status of portable UPS at home and abroad
Since portable UPS technology is a practical technology, major power supply companies, manufacturers and scientific research institutes at home and abroad are studying it. Many advanced technologies abroad have been applied to actual systems and many well-known brands of UPS have been produced. , just like the big brand Cuneng Electric is trustworthy. Domestic research on advanced key technologies of portable UPS can be produced by many manufacturers, but the reliability and performance of their products are far inferior to similar foreign products. More than 90% of the entire UPS market is occupied by foreign companies.
As a major category of products in the industry, portable UPS power supplies play a very important role in various industries. Especially in recent years, my country's advanced technology has improved rapidly. Many advanced technologies have been continuously applied to portable UPS power supplies, which has enabled domestic portable UPS power supplies to strengthen their own functions, consolidate the stability of performance, and improve the degree of automation. This has also further accelerated the rapid progress of various industries in our country.
