Incentives for intense competition in the inverter market

With the continuous improvement of industrial automation, the frequency converter has been widely used. In simple terms, the frequency converter is the application of frequency conversion technology and microelectronics technology, by changing the frequency of the motor power supply to control the power control equipment of the AC motor. The frequency converter is mainly composed of rectification, filtering, inverter, brake unit, drive unit, and detection unit micro-processing unit. The inverter also has many protection functions, such as over-current, over-voltage, overload protection and so on.

It has been more than 30 years of R&D and application of science and technology since the manufacture of the first inverter in our country. With the increase in the level of electronic technology and the needs of the market, there are more and more kinds of frequency converters and more and more functions. perfect. Various inverter manufacturers have launched double competition in price and quality. In this competitive atmosphere, what kind of development track will the inverter enter? What kind of new situation will the industry develop?

The general purpose of the inverter is to adjust the speed, and reduce the starting current to save energy and reduce consumption. The different operating voltages of the equipment have different requirements for the inverter. At present, the frequency converter on the market is roughly divided into three types: high, medium and low voltage. No matter which kind of inverter, the manufacturers are all heading towards the same goal, that is, high performance, multi-function, and small size. This is also the demand of inverter users. Therefore, the manufacturers of inverters will The development and production of their respective inverters have brought new requirements.

For the inverter, the performance of the inverter mainly depends on three aspects. The first is the effect of the output voltage harmonic on the motor, the second is the harmonic pollution and input power generated by the power grid, and the third is See how the energy consumption of the inverter itself. The basis for judging these points is that not only must the inverter be intelligent and modularized, but it must also reduce the losses caused by the use of the inverter and the switching process of the equipment. These aspects have not only become the main embodiment of determining the quality of inverters, but also the priority for inverter manufacturers to continuously develop and improve.

Nowadays, the functional requirements of the society for products are getting higher and higher, and a single application field can no longer meet the needs of a wide range of users. Therefore, in order to meet the challenges brought about by different application fields, inverters need not only continuous upgrading, but also need Maximize the diversification of products to meet the needs of different application areas. The fields in which inverters are now applied include various industrial productions, urban water supply systems, and household appliances. In these fields, not only the performance of the inverter is required to be stable, but also products with full digital, systematic, and networked functions are needed. The R&D and production of such products not only represents the progress of frequency conversion technology, but also brings more for production and life. The cheaper, more industry to promote further development.

The inverter industry has been unprecedentedly developed and applied in modernization such as cement, elevators, printing, and electricity, as well as medicine, communications, transportation, transportation, electric power, electronics, and environmental protection. Almost all industries in the national economy are inseparable from inverters. As a whole, the competition in China's inverter industry is increasingly fierce.

The various information technology innovations and fierce competition in the market have brought about considerable development momentum and space for the inverter industry. A new round of inverter innovation will intensify, and the inverter market will enter a period of rapid growth.
