Variable frequency drive market analysis

With the rapid development of power electronics technology, computer technology, and automatic control technology, electric drive technology is facing a new revolution. In the field of electrical transmission frequency control system, high efficiency and good performance into the mainstream. Benefit from energy conservation, the pull of the green strategy, as the VVVF important equipment, variable frequency drive industry has become a huge market potential in the next few years one of the industries.

Variable frequency drive technology new trends
The development of information technology has led to the development of variable frequency drive technology, frequency conversion speed and high precision, start low energy consumption, small footprint, state-of-the-art technology, feature-rich, easy to operate, versatile, easy to form a closed-loop control, is considered the ideal speed control programs on behalf of the development direction of the electric drives.

The high-voltage high-power variable frequency drive for its electromagnetic compatibility, electromagnetic radiation, tandem technology, there is a lot of technical difficulty of development, and therefore also become a hot spot of the world's major electrical companies compete. At present, many domestic variable frequency drive manufacturers are in the field of high-voltage VFD to put in a lot of manpower and material resources, and strive to occupy the high ground in the current VFD drive technology. Nevertheless, the core of the device of the variable frequency drive is always dependent on imports has become a bottleneck restricting the development of domestic variable frequency drives.

Challenges from different application areas, the variable speed drive are constantly upgrading, more and more diverse products. Overall, the new generation of VFD should have the following characteristics: The first all-digital, fully functional, able to compensate for load changes, especially distributed communication, networking functions and has a programmable function. Is a simple variable frequency drive or industry-specific as well as the mechanical and electrical integration, miniaturization. Network and systematized, to reduce the cost of production through a network connection, the fieldbus module, the different models of the VFD drives to be configured with a programming language and the communication protocol.

In addition, along with the advent of new high-voltage power electronic devices, high-voltage and medium-voltage variable frequency drive has developed by leaps and bounds. In the next few years, the matrix converter, variable speed drive and other green new drive will be available soon.

China domestic variable frequency drive status quo
Variable frequency drives manufacturers in the domestic market of more than 300. VFD supporting industries in China is relatively weaker domestic brands in terms of manufacturing, industrial design and other technical aspects with foreign brands there are some gaps. Currently, foreign brands in the domestic VFD market share of about 7 percent, products the local variable frequency drive enterprise main production of the V / F control, vector drives for superior performance, high technical content, the vast majority of domestic companies to develop products not mature enough.

Therefore, the variable frequency drive market in China is still the main price-oriented, but with the rise of local brands, a domestic market share of the enterprise is gradually expanding, especially in recent years, the trend accelerated alternative to foreign brands. Although not yet have the strength to carry out comprehensive and international top-brand competition, but in some product segments and market shows a certain degree of competitive advantage, market share gradually expanding.

On the whole, the variable frequency drive industry in China is increasingly competitive. Attractive market, not only the market has formed a certain scale and potential capacity is also very impressive, the industry continues to attract new participants.

With the technological advances enhance the stability and quality of the domestic manufacturers, and service and price advantage, is expected in the next few years the monopoly of foreign manufacturers of high-end products, the market situation has changed.

China variable frequency drive market prospects
Development of VFD technology, unprecedented promotion and application in the field of electricity, cement, elevator, mining, metallurgy, transportation modernization.

According to the China Association of Industrial Electrical variable frequency drive branch statistics, in recent years, China's VFD drives market annually needs about a 100 billion market space. Moreover, with the progress and diversification of user demand, domestic variable speed drive products constantly improve and increase integration and systematic increasing, and there have been some special AC drive products, which are for our laid the foundation for further expansion of the VFD market.

The data show that in recent years, China's variable speed drive market has maintained a growth rate of 12% to 15% expected at least in the next five years, the AC drive market demand will maintain a growth rate of more than 10% of. And after 10 years, the drives market reach to saturation.

Our variable frequency drive total potential market space for about 120 billion to 180 billion Yuan, which accounted for about 60% of the market share, atmospheric drive, high voltage AC drive needs of a relatively small number, but due to a single variable frequency drive power, the price is high, only about 40% of the market. With changes in load current domestic motor with energy-saving potential of at least 180 million kilowatts, and thus provides a very huge market for variable frequency drive applications.
