subject: Inverter Technology Development And Needs Analysis - Electron Devices, Frequency Converter - The [print this page] Opportunities and challenges: Devices rely on imports into the domestic core bottleneck of the development
High pressure and medium pressure Inverter Have come a long way
Market prospectsMarket data:Demand in China each year about 10 billion yuan market space form
With the power Electronic Technology, computer technology and the rapid development of automatic control technology,
Electric Drive technology is facing a new revolution. In the field of electric drive, variable speed system for high efficiency, good performance and into the mainstream. Benefit from energy saving, green
Environmental protection Strategy of pulling such as frequency control of the important equipment, inverter industry has become a huge market potential of the next few years one of the industries.
New Trends transducer technologyDevelopment of information technology led the development of inverter technology, frequency control due to high precision with speed, start low energy consumption and small footprint, advanced technology, feature-rich, simple, versatile, easy to form a closed loop control etc., is considered the best speed program, on behalf of electric transmission development.
High voltage power converter because of the electromagnetic compatibility, electromagnetic radiation, series technology, and technology development there is very difficult, it has become the world's major electric company competition hot. Currently many converter manufacturers are investing in high-voltage inverter lot of manpower and material resources, and strive to inverter technology in the current occupation of high ground. Nevertheless, the main components is always dependent on imports, a bottleneck restricting the development of domestic inverter.
Response to challenges from different applications, inverter are also constantly upgrading the products more diverse. Overall, the new generation of inverter should have the following characteristics: First, all digital, fully functional, able to compensate the load changes, particularly with distributed
Communicate , Networking, and a programmable function. Second, simple or industry-specific frequency converter and the realization of the mechanical and electrical integration, miniaturization. Third, networking and systematic reduction of production costs through the network connection, through the field bus module, the different types of converter to the same programming language and communication protocol configuration.
In addition, with new high-voltage power
Electronic Devices The advent of high-voltage and medium voltage inverter has made great progress. In the next few years, matrix converters, inverter and other new green converter will soon be available.
Status of domestic inverter Converter domestic market more than 300 manufacturers. As the transducer supporting our industry is relatively weak, and domestic brands in terms of manufacturing, industrial design technology, there are some gaps with foreign brands. Currently, foreign brands in the domestic market share of about 7 inverter into, local enterprises mainly produce inverter V / F control products, for the superior performance of vector frequency high technical content, most domestic companies to develop products also not mature enough.
Therefore, the inverter market in China continues to price-oriented, but with the rise of domestic brands, domestic inverter company's market share is gradually expanding, especially in recent years appears to accelerate the trend of alternative to foreign brands. Although not yet have full international luxury brand strength to compete to start, but in some product and market segments show a certain degree of competitive advantage, market share gradually.
A whole, the current inverter industry in China increasingly fierce competition. As the market very attractive, not only the market has formed a certain scale, but also very substantial potential capacity, the industry continues to attract new participants.
