2010-2021 IGBT Global Value

Frequency converter is the application of frequency conversion technology and microelectronics technology, by changing the frequency of the motor power supply to control the AC motor power control equipment. Frequency converter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, driving unit, detection unit microprocessor unit and so on. Frequency converter products are energy-saving power electronic equipment, for the state to support the development of high-tech products, has long been the national industrial policy to encourage and support. National "Twelfth Five-Year Plan" (2011-2015) to "Fourteenth Five-Year Plan" (2021-2025) process, inverter in the country's energy-saving emission reduction planning has been playing an important role. Frequency converter in energy saving and emission reduction has a great role in promoting, in line with the national energy saving and emission reduction and industrial greening planning arrangements, therefore, with the low-voltage frequency converter related planning policies and national energy saving industrial energy saving and emission reduction is inseparable. In addition, the "14th Five-Year Plan" in energy saving and emission reduction requirements, but also the transformation and upgrading of the frequency converter has put forward higher requirements.
The application field of frequency converter covers many industries of the national economy. Due to the advantages of high precision, advanced technology, rich functionality, high reliability, easy operation and strong versatility of frequency converter, it is superior to any previous speed control methods, such as variable pole speed control, voltage control, slip speed control, series speed control, rectifier motor speed control, hydraulic coupling speed control, etc., and therefore in the electric power, public works, textile and chemical fiber, building materials, petroleum, chemical industry, food and beverage, tobacco, coal, machining, etc., the frequency converter is in the electric power, utility engineering, textiles and chemical fibers, building materials, petroleum, chemical industry, food and beverage, tobacco, coal, machining, etc., the frequency converter has been used for the development and upgrade of the national economy. Therefore, in electric power and public works, textile and chemical fiber, building materials, petroleum, chemical, food and beverage, tobacco, coal, machinery processing and other industries, frequency converters are playing an important role.

The upstream industry of frequency converter mainly includes frequency transformer, semiconductor components (IGBT), cabinet, automation instrumentation and other enterprises, are fully competitive industry. Among them, IGBT semiconductor components are mainly dependent on imports, which are basic components, accounting for the low cost of inverter products and sufficient supply. Therefore, the inverter industry is less constrained by the upstream.

Upstream of the inverter industry in general, the main raw materials of the products are transformers, IGBTs, capacitors, shells and so on. Direct material costs of inverter-related companies account for more than 90% of the cost of the main products, and fluctuations in raw material prices have a greater impact on the company's operating results. If the main raw material market supply and demand changes or abnormal fluctuations in procurement prices, will have a greater impact on the company's operating results.

At present, the main raw materials in the IGBT and the chip is mainly used in foreign brands, although some domestic enterprises have developed and produced IGBT power modules and chips, and in recent years, technological progress is greater, but the market user recognition of domestic brands is not as good as imported brands. In recent years, China's production technology continues to improve, and the distance between foreign products is narrowing, IGBT localization process to speed up the monopoly of foreign manufacturers gradually be broken, China's IGBT is expected to get rid of import dependence. From the market scale, Infineon's annual report disclosed data for the standard measurement of the global IGBT market size, with the development of the global IGBT industry in recent years, the global IGBT market size of about 7.09 billion U.S. dollars in 2021, a year-on-year growth of 6.8%.

From the perspective of downstream applications, inverters have rich application fields, and the main application fields of different types of inverters are different. High-voltage inverter is widely used in metallurgy, electric power, water supply, petroleum, chemical industry, coal and other fields; medium-voltage inverter applications are similar to high-voltage inverter, in addition to metallurgy, electric power, petrochemical and other industries, medium-voltage inverter can also be used for wastewater treatment; domestic low-voltage frequency converter applications are more dispersed, and is now widely used in elevators, cranes, machine tools, textile machines, air conditioning and other fields.
