The development of frequency converter in China has been more than 20 years. Up to now, except for a slight decrease in 2015, the domestic frequency converter market has always maintained a rising trend.  In the face of the double pressure of the market and foreign enterprises, domestic inverter manufacturers must seize the development opportunities of The Times and find the right direction to break through the siege. 

Frequency converter: an application of frequency conversion and micro-electronic technology to control the ac motor power control equipment, in real use with speed regulation, energy saving and other functions, has a pivotal role in the development of modern industry. 

In recent years, with the continuous innovation of automation, electronic power, artificial intelligence and other technologies, as the key equipment of motor speed regulation and energy saving, frequency converter has also ushered in considerable development, the continuous improvement of industrial automation, so that frequency converter has been more and more widely used.  

Development status of domestic frequency converter 

The development of frequency converter in China has been more than 20 years. Up to now, except for a slight decrease in 2015, the domestic frequency converter market has always maintained a rising trend. 

Relevant data show that in 2017, the size of China's inverter market reached 45.32 billion yuan, with an average compound growth of 8.74% in four years. Compared with 41.677 billion yuan in 2016, the overall development can be said to be stable and rising. 

However, in recent years, the growth of the low-voltage inverter market, which accounts for 60% of the market, has been weakening, and the overall growth of the domestic inverter market has slowed down slightly, which is seriously contrary to the view of many experts that "the inverter market will usher in a saturation period after ten years". Affected by the gradual maturity of technology and the low entry threshold, the industry development is in a highly homogeneous and chaotic competition stage. Although the advantages of the leading enterprises in the industry have been established, the competition of the middle and lower enterprises is increasingly white-hot, and the market segmentation war and price war continue, and the industry development is chaotic. In addition, in the case of fierce internal competition, foreign brands quietly occupy more than 95% of the domestic inverter market share, because of the gap in technology, quality and other aspects of the local brand is difficult to compete, the living space is greatly squeezed. 

Intelligent, digital, integrated into the future development direction 

In the face of the double pressure of the market and foreign enterprises, domestic inverter manufacturers must seize the development opportunities of The Times and find the right direction to break through the siege.  Now, the age is given priority to with hardware competition has become the past, in the "made in China 2025" and "4.0" industrial development strategy, the network of production and the manufacture is becoming an important direction of digital, make realistic manner via the Internet virtual rendering, to implement the intelligent of the bricks, digital will become the future direction of development. 

On the basis of intelligence, the inverter related functional components, such as PLC controller, PID controller and communication unit, are effectively integrated together to form a multi-functional, high reliability, small and micro integrated machine, which will be another trend of inverter development in the future.
