    Frequency converter, a kind of power control equipment that uses variable frequency technology and microelectronic technology to control AC motor, has been in the development history in China for nearly 30 years. In these decades, inverters have achieved certain results in terms of industry scale, application areas and product functions.

    Market Overview: Steady progress, the domestic market will usher in a new wave of foreign investment

    At present, the green industry boom in the world has risen. As an energy-saving component, the inverter has ushered in a new opportunity. However, many people in the industry said that as far as the overall market development is concerned, as the industrial bottleneck has not yet broken through, at least after 10-15 years, the domestic inverter industry can enter a mature period. As far as the domestic market is concerned, in recent years, the performance of the inverter has been relatively stable, with the growth rate of around 14% and the potential market of about 150 billion yuan. From the perspective of market segments, the market growth rate of medium and low voltage inverters has reached a maximum of 15%. In comparison, the growth rate of high-voltage inverters is staggering, reaching more than 40%.

    As the market demand continues to grow, the growth rate of the inverter market in 2018 is still stable. However, it is worth mentioning that the expansion of the domestic market will certainly attract more foreign brands. In the next few years, local enterprises will face a new round of industry competition. How to occupy and firmly hold the existing market share will become a nation. Brands should be carefully considered next.

    Application areas: continuous expansion, from small appliances to large machinery full coverage

    At present, the acceleration of industrial automation is driving the expansion of inverter applications, from small appliances to large-scale mine grinders and compressors, mainly in air conditioning loads, crusher loads, compressor loads, rolling mill loads, etc. field. In terms of air conditioning load, the frequency converter mainly plays a role as a node. Through the frequency conversion device, the refrigeration pump, the cold water pump and the fan that drive the air conditioner operate, thereby achieving the effect of scheduling the power transformation. With the widespread use of frequency converters, inverter air conditioners are becoming more and more common in everyday life. In addition, applications such as spinning machines, mixers, paper machines, injection molding machines, etc. are more inclined to industrial automation, and may not be as close to life as inverter air conditioners, so they are not well known. However, the position of the inverter in industrial manufacturing is self-evident.

    Industrial bottleneck: chaos, core competitiveness and brand influence need to be improved

    The reason why domestic inverters have not matured is precisely because the current inverter market is still facing many industrial bottlenecks. Specifically, on the one hand, it is difficult to break through cutting-edge technology. At present, domestic inverters are still in the primary growth stage, and more efforts are made in the low-end market. The high-end market is rarely involved. On the other hand, in the past few years, the inverter market has been continually fighting. In order to build its own competitive advantage, the company has fought a price war, but has neglected the consideration of product quality, performance and user demand, resulting in market chaos; Enterprises that have not made long-term plans for their immediate interests have also hindered the progress of the entire industry to some extent. In addition, foreign brands have long occupied the domestic market and presented challenges to local brand building. At present, foreign brands occupy more than 95% of the domestic inverter market, and local brands are still difficult to compete with, and the living space is gradually decreasing. It can be said that the rise of national brands is imminent.

    Future development: to overcome difficulties, to move toward intelligent, high-end, customized

    In the face of the current development situation of domestically produced inverters, if the inverter wants to achieve rapid development and enters the mature period within 10 years, it should first seize the development opportunities of the intelligent era, and then aim at the industrial pain points, and each breaks. It is expected to achieve a new leap. From a technical point of view, it is impossible to completely abandon the traditional technology to achieve intelligent transformation. Therefore, it is necessary to base on the existing technology foundation, combine traditional technology with modern technology, and transform from asynchronous machine control to synchronous machine control. Breakthrough and innovation in high-end inverter technology. At the same time, customization will become one of the important directions for the future development of the inverter. New eras and new market demands will present new challenges. The frequency converter will change its time and take a customized route, not only providing customers with personalized solutions, but also extending the application range of the products. As many traditional industries in China have just entered the transformation stage, or are in the preparation period before the transition, the market demand is gradually slowing down. Therefore, the development of the domestic inverter industry does not have to be eager to achieve success. Striving for stability is the best state of the market, and intelligence The high-end, customized, and customized will become the main offensive direction of the inverter in the future.
