In the 1980s, foreign inverter products began to enter the Chinese market, and with the rapid development of the Chinese economy and the increasing awareness of energy conservation and environmental protection, the application of inverters in China has become increasingly popular since the 1990s, and the industry scale has rapidly expanded. It has been widely used in various industries such as finance, energy, transportation, chemical industry, textile, education, and healthcare. Variable frequency drive is a high-tech product with high technological content, high added value, and high return on investment, which conforms to the national industrial development policy.
Frequency converter is a key equipment for energy conservation. According to online media statistics, there are currently at least 180 million kilowatts of motors with variable loads and energy-saving potential in China, providing a huge market for the application of frequency converters. In addition, due to the emergence of new high-voltage power electronic devices, high-voltage and medium voltage frequency converters have also made significant progress.
At present, foreign brands still dominate the Chinese medium and low voltage inverter market. Mainly ABB, Siemens, Fuji Electric, Mitsubishi Electric, Yaskawa Electric, Delta, Schneider, Emerson, Danfoss, Sanken AB、 Vasa and other brands occupy the top 12 in China's medium and low voltage inverter market, with the smallest annual sales of around 200 million yuan. The largest domestic brand, Envision, has already ranked behind 13th place, while other companies have smaller scales. Frequency converter products generally have a maturity period of about 3 years. Whether the quality is reliable and the performance is stable needs to be tested by the customer's usage time. Due to the relatively short history of most local enterprises and the ongoing improvement of their product lines, many new products have entered the market for a short period of time, making it difficult to compete with internationally renowned brands with a long history in terms of product maturity and brand awareness. In addition, due to the particularity of China's medium and low voltage frequency converter market, foreign brands are biased, which has a negative impact on domestic brands' participation in market competition. Of course, in the early stages of domestic brand development, there were indeed some products with poor quality, reliability, and stability, which affected the industry reputation of domestic brands. In recent years, with the growth and rapid improvement of comprehensive strength of local enterprises, the reputation of domestic brands has significantly improved. However, to completely change the overall impression of users, it still requires the joint efforts of production enterprises and the test of time.
After experiencing rapid growth in 2007, the development trend of the frequency converter market became more subtle in 2008 due to factors such as the appreciation of the Chinese yuan and macroeconomic regulation. Most suppliers expressed concerns about the impact of macroeconomic regulation on the market.
Frequency converter is a key equipment for energy conservation. According to online media statistics, there are currently at least 180 million kilowatts of motors with variable loads and energy-saving potential in China, providing a huge market for the application of frequency converters. The application of frequency converters has expanded from common fans, water pumps, etc. to food, beverages, logistics, buildings, etc., constantly opening up new energy-saving fields. Its functions have also been improved and diversified. On the one hand, it is fully digital, fully functional, and can compensate for load changes with adaptive and self-tuning technology, especially distributed high-end frequency converters with communication, networking functions, and integrated PLC; On the other hand, there are simple or industry-specific frequency converters, as well as electromechanical integrated and miniaturized frequency converters. In addition, due to the emergence of new high-voltage power electronic devices, high-voltage and medium voltage frequency converters have also made significant progress.
