Inverter is a high technology, high added value, high return of high-tech products. Has been as an important means of saving energy, improving technology, improving equipment operation, protection of production systems, improve production quality. With the development of automation, power electronics and other technologies, the frequency converter, as the key equipment of motor speed regulation and energy saving, plays an important role in many fields. Since entering the "12th Five-Year Plan", energy conservation and emission reduction are the key to the development of all walks of life. The frequency converter enables the motor and its drag load to adjust the speed output according to the production process without any change and reduce the motor work Consumption, to achieve the purpose of efficient system movement. Enterprises in order to resist the pressure of price increases, the Chinese home for all sectors to develop energy-saving goals, I believe inverter applications will be more extensive, the market prospects.

With the rapid development of power electronic technology, computer technology and automatic control technology, electric drive technology is facing a new revolution. In the field of electrical transmission, frequency control system due to high efficiency, good performance and become the mainstream. Benefit from energy-saving emission reduction, green strategy driven, as an important frequency control equipment, inverter industry become the next few years, the market potential is very huge one of the industries.

Shang Pu consulting electronics industry analysts believe that with the rapid development of the national economy, the domestic demand for inverter products is also growing. Inverter with its energy saving features, will be strongly supported by national policy. China's inverter development was policy-oriented, industry-focused features. At present, most of the enterprises in our country use inverters and purchase inverters in advance, all rely on the support of national policies. Without the state's supportive policies, the expansion of the inverter industry will slow down. China's inverter industry is mainly concentrated in the metallurgical, water supply, petroleum and other heavy industry, these industries are because of the country's pillar industries, so a greater chance of supporting funds, and some other light industry, the application of inverter relative ratio slightly less.

According to Shangpu Consulting's "2011 China Inverter Manufacturing Industry Analysis and Research Report" shows that at present, the general frequency converter energy-saving rate of 20% -30%, and some even more than 50%. With the frequency conversion technology The rapid development of frequency converter and the expansion of product functions, the frequency converter in the cement, elevators, printing, power and other modern industries and medical, communications, transportation, transportation, power, electronics, environmental protection and other fields have been the unprecedented development of China's drive market has reached 731 100 million yuan, promising industry prospects.

Inverters in the field of energy-saving emission reduction has a huge unique advantages, Delta inverter agents - Jinan Quan Jie that the inverter business should be "through the 12th five-year energy-saving emission reduction to better establish the concept of energy-saving products will be The energy-saving performance of a higher level, which is for the future development of inverter business identity is beneficial.

Inverter technology trends

The development of information technology has led to the development of inverter technology. Because of its features such as high speed regulation, low starting energy consumption, small footprint, advanced technology, rich functions, easy operation, high universality and easy formation of closed-loop control, Is considered the best speed control program, on behalf of the direction of the development of electrical transmission.

Because of its high technical difficulty in electromagnetic compatibility, electromagnetic radiation and tandem technology, high-voltage high-power inverter has also become the hot point of competition among major electric companies in the world. At present, many domestic inverter manufacturers are investing a lot of manpower and material resources in the field of high-voltage inverter, and strive to occupy the commanding heights in the current inverter technology. In spite of this, the inverter core components have always been dependent on imports, becoming a bottleneck restricting the development of domestic inverter.

In order to meet the challenges from different application areas, frequency converters are constantly updated and the products are more and more diversified. In general, a new generation of inverter should have the following characteristics: First, all-digital, full-featured, to compensate for load changes, especially distributed with communication, networking and programmable features. Second, simple or industry-specific inverter and to achieve a mechatronic, miniaturization. Third, networked and systematic, through the network connection to reduce production costs, through the fieldbus module, the different types of frequency converter with the same programming language and communication protocol configuration.

In addition, along with the advent of new high-voltage power electronic devices, high-voltage and medium-voltage converters have also made great strides. In the next few years, new inverters such as matrix inverters and green inverters will be available soon.

Domestic inverter status quo

At present, there are more than 300 frequency converter manufacturers in the domestic market. Due to the relatively weak strength of China's inverter supporting industries, domestic brands no matter in the processing and manufacturing, industrial design and other technical aspects with foreign brands there is a certain gap. Currently, foreign brands in the domestic inverter market share of about 70%, the local inverter business mainly produces V / F control products, for superior performance, high technical content of the vector inverter, the vast majority of domestic enterprises also developed products Not mature enough.

Therefore, the inverter market in China is still based on price orientation. However, with the rise of local brands, the market share of domestic inverter manufacturers is gradually expanding. Especially in recent years, there is a trend of accelerating the substitution of foreign brands. Although not yet fully competitive with the top international brands, it shows some competitive advantages in some sub-products and markets, and its market share has gradually expanded.

As a whole, the competition in China's inverter industry is getting fiercer. Due to the attractive market, not only has the market reached a certain size, but also its potential capacity is very impressive, attracting new participants in the industry.

With the technological advancement of domestic manufacturers and the improvement of quality and stability, as well as the advantages in terms of service and price, the market situation in the next few years in which high-end products are monopolized by foreign manufacturers will be improved.

Converter market prospects

Inverter technology, so that the inverter in the power, cement, elevators, mining, metallurgy, transportation and other fields of modernization has been an unprecedented promotion and application. According to the statistics of China Association of Inverter Drives Branch, in recent years, China's inverter market needs about 10 billion yuan of market space every year.

Moreover, with the improvement of user needs and diversification, the functions of domestic inverter products are constantly improving and increasing, and the degree of integration and systematization is also getting higher and higher, and some special inverter products have appeared, all of which are for our country Inverter market to further expand laid the foundation.

Data show that in recent years, China's inverter market has maintained a 12% to 15% growth rate is expected at least in the next 5 years, the inverter market demand will continue to maintain 10% growth rate. In 10 years, the inverter market can be saturated.

The total potential market for inverters in China is about 120 billion to 180 billion yuan, of which the market share of atmospheric pressure inverters accounts for about
