Chinese domestic VFD (Variable-frequency Drive) may usher in industrial changes
With the continuous improvement of the technical field, the thyristors of VFD (Variable-frequency Drive) have also been innovated from generation to generation, and Chinese VFD (Variable-frequency Drive) industry is also ushering in a change in the process of catching up with similar foreign products.
Entering the 1980s, the global VFD (Variable-frequency Drive) technological change accelerated, and the mature frequency conversion products were widely used in various industries of the national economy. As China becomes the world's factory, the rapid development of the manufacturing industry has provided more and more market space for VFD (Variable-frequency Drive) products. However, today, Chinese domestic VFD (Variable-frequency Drive) market can still be said It is dominated by foreigners, and Japanese, European and American brands have divided up 80% of the market share. However, in recent years, Taiwanese inverter brands have also shown some strong performance, and Chinese domestic brands are still in a weak position overall.
In the past few decades, power electronic devices have evolved from the initial SCR (thyristor), GTO (gate turn-off thyristor), through BJT (bipolar power transistor), MOSFET (metal oxide field effect transistor), SIT ( Static induction transistor), SITH (static induction thyristor), MGT (MOS control transistor), MCT (MOS control thyristor), developed to today's IGBT (insulated gate bipolar transistor), HVIGBT (high voltage insulated gate bipolar thyristor), The update of devices promotes the application of VFD (Variable-frequency Drive) in a wider range, and the market scale expands rapidly.

However, Chinese domestic frequency conversion was once "10-15 years" behind foreign countries. After catching up in recent years, not only has a great breakthrough in technology, but the development of many Chinese domestic frequency conversion is also in line with international standards. Enterprise Competitiveness. INVT, Energy, Anbangxin, Sunwoele, Zhiguang Electric and other Chinese domestic inverter manufacturers have begun to occupy more and more market shares by virtue of their price advantages. However, it is undeniable that the core factor that really determines whether Chinese domestic inverters are competitive is technology. Level.
Over the years, the National Development and Reform Commission of China has been cooperating with relevant state departments to give key support to the technical development and transformation of frequency conversion, organized the evaluation and recommendation of frequency conversion speed regulation technology, and encouraged relevant units to focus on development and demonstration projects. Relying on this, Chinese domestic frequency conversion speed regulation technology has been developed and promoted to a certain extent. For China, the industrialization process has not yet ended, and the high energy-consuming industries account for a large proportion, which will continue to promote the continuous and rapid growth of Chinese energy demand. The high energy consumption of industries is large, and Chinese national energy-saving and emission-reduction policies also make Chinese domestic VFD (Variable- Frequency Drive) enterprises have more opportunities.
Chinese domestically produced frequency converters are expanding in market, technology is improving, and talents are increasing. With the strengthening of Chinese state support and the growth of investment in private enterprises, Chinese domestically produced frequency converters will surely usher in their own "spring". However, don't rush to be happy. In order to make the "spring" last longer, it is necessary to improve the technology, that is to say, to constantly surpass the technology. Only in this way can we ensure that Chinese domestic frequency conversion stands in the green forest of frequency conversion. What makes us feel gratifying is that Chinese domestic inverter companies, represented by Sunwoele, are continuously increasing their investment in human, material and financial resources. I think that in the next few years, Chinese domestic frequency conversion will become the world's frequency conversion.
