Analysis of the current situation of the domestic inverter market

nowadays, the inverter industry has developed rapidly, and the inverter products have initially formed industrialization. Looking at the development of the international inverter field, the world's well-known brand manufacturers have also moved to China to implement the localization strategy and expand their sales in China. The frequency converter manufacturers growing up in China have also gradually developed and matured in the gap between European and American brands and Japanese and Korean brands, and the competition in the whole frequency converter market has become white hot

frequency converters have been widely used in major industrialized countries since they came out in the 1960s and 1980s. Since the 1990s, with the strengthening of people's awareness of energy conservation and environmental protection, the application of frequency converters has become more and more popular. Compared with industrialized countries where such problems are found, China's inverter industry started relatively late. In the mid-1980s, the annual sales volume of frequency converters in China was only tens of millions of yuan, almost all of which were foreign brands. After more than ten years of promotion and the market value of plastic machinery orders in the United States in the fourth quarter increased by 3 percentage points compared with the third quarter of 2013, the frequency converter was recognized by the majority of enterprise users, and it was only in the 1990s that the frequency converter was introduced into China on a large scale

with the deepening of domestic enterprises' understanding of frequency converters and the entry of a large number of foreign products, China's frequency converter market has been rapidly launched. Industry insiders estimate that the sales volume of China's inverter industry was about 3.5 billion yuan in 2001 and 4.2 billion yuan in 2002. The internationally renowned authoritative arc Organization predicts that the market capacity of AC speed regulating devices in China in 2002 will be US $1billion, of which the market capacity of medium and high-power products will be US $200million, and it is predicted that it will develop at an annual growth rate of 15% to 20%. In 2003, the market sales of frequency converters in China exceeded 5billion yuan, of which the sales of atmospheric (low-voltage) frequency converters reached 4billion yuan, and its development prospect is quite optimistic

the total potential market capacity of frequency converters in China should be 120-180 billion yuan, of which atmospheric frequency converters account for about 60% of the market share, and the demand for medium and high voltage frequency converters is relatively small. However, due to the high power and high price of a single frequency converter, it should account for about 40% of the market share. At present, high-voltage frequency converters are widely used in industries such as metallurgy, petrochemicals, power plants, urban water supply and building materials. The main equipment used is fan and pump loads. Due to the constraints of high-voltage power electronic devices, the application has not been widely carried out and needs to be further promoted by enterprises. At present, the market share is less than 20%

as a new high-tech product, foreign brands have occupied most of the market from the beginning. At present, the domestic inverter market sales is about 10000 kW per year, 90% of the market share is occupied by the products of manufacturers in the United States, Japan and Europe, and domestic inverters account for a small market share; Products are mainly from Japanese manufacturers such as Mitsubishi, Fuji, Toshiba, Yaskawa, Hitachi and Panasonic, while Siemens, abb and Schneider in Europe also occupy a large market share. There are about 90 brands of frequency converters active in China (among which domestic brands account for about 70%). Japanese companies entered China early, made in-depth and careful investigation and Research on the Chinese market, and launched targeted products suitable for China's national conditions. At present, the market share is the highest, up to more than 40%; European and American companies came in late, but their products are high-grade, large capacity and expensive, accounting for about 30% of the market share; Another 10% of the market share is occupied by Taiwan products

in recent years, there are many domestic manufacturers, and their market share has increased year by year. The total market share should exceed 20%, mainly concentrated in low-end frequency converters. Because the manufacturing technology is less than that of developed countries, The quality of power switching devices is difficult to compete with developed countries. The technology of the whole inverter is backward, and the grade of domestic inverter is low, mainly low-voltage (400V) and small capacity (within 315KW) products. Compared with the international advanced frequency conversion and speed regulation technology, the backward production technology of frequency converter in China is manifested in many aspects. First of all, the manpower and material resources invested in the research of frequency conversion technology are not concentrated, and there is no market competitiveness, which is the root of backwardness. Secondly, the backward supporting industries and processing equipment are difficult to adapt to the development of inverter production. Domestic frequency converters lag behind foreign countries in both product performance and appearance design

compared with powerful foreign manufacturers, it is not enough to rely on one or two national enterprises to support the development of domestic national enterprises. Only relying on the preparation technology of fence type aluminum lead alloy composite anode for non-ferrous metal electrowinning developed by guopiyi's team at Kunming University of science and technology, the enthusiasm of some people of insight, with limited funds, cannot form a strong market competitiveness, and the state also needs to give macro guidance from the policy, We must establish a good operation mode and establish the brand image of domestic brands. Only by strengthening basic research and increasing investment in frequency conversion technology research can we fundamentally change the current backward situation of domestic frequency converters, so as to avoid large losses caused by loose fasteners and form a large industry to serve the society
