It is reported that IGBT has the advantages of small driving power, large current capacity, high switching frequency, simple control circuit, and low loss, and is an ideal power semiconductor. With the advancement of science and technology, the types of large electrical equipment are increasing and the scope of applications is expanding. The demand for high-voltage and high-power IGBT modules with high voltage and high current is also growing. High-voltage and high-power IGBT modules can be widely used in high-voltage power transmission, photovoltaic power generation, wind power generation, industrial control, electric vehicles, rail transportation, aerospace and other fields.
High-voltage and high-power IGBT modules began to be developed and applied in the 1990s, and were first used in the rail transit field. Later, as the scope of applications gradually expanded, the market's requirements for the stability and reliability of high-voltage and high-power IGBT modules became increasingly stringent. At present, the application scope of high-voltage and high-power IGBT modules in high-tech industries is still expanding. Silicon materials have been mainly used in their manufacturing. In order to further improve performance, the application proportion of new-generation semiconductor materials such as silicon carbide continues to increase.
In the field of high-voltage power transmission, the high-voltage DC power transmission technology of high-voltage and high-power IGBT modules is increasingly mature. Compared with the traditional thyristor power transmission technology, it takes up less space, has high flexibility and large transmission capacity. In the field of electric vehicles, high-voltage and high-power IGBT modules can be used to manufacture DC/DC converters. DC/DC converters are indispensable auxiliary electronic equipment in electric vehicles. Their function is to convert the high-voltage electricity output by the power battery into low-voltage Electricity powers the car.
In addition, UHV DC transmission has the advantages of large transmission capacity, long transmission distance, low loss, multi-power supply, and multi-point power reception. It is in line with the development trend of the power industry, and the scale of its installation in my country is rapidly expanding. my country's electric vehicle industry is booming. According to data released by the China Automobile Association, my country's pure electric vehicle production will be 2.761 million units in 2021, a year-on-year increase of 178.8%. From the perspective of UHV DC transmission system and electric vehicle market alone, my country's high-voltage and high-power IGBT modules have broad development prospects.
According to the "2023-2027 China High-voltage and High-Power IGBT Module Industry Market In-depth Research and Development Prospects Forecast Report" released by the New Sijie Industrial Research Center, in general, the technical barriers to high-voltage and high-power IGBT modules are constantly improving, and now Stage: Globally, there are only a small number of companies capable of mass-producing high-performance, high-voltage and high-power IGBT modules. They are mainly German Infineon, Swiss ABB, Japanese Mitsubishi Electric, Japanese Hitachi, Japanese Toshiba, etc., mainly European and Japanese companies. . Driven by the rapid development of downstream industries, my country's development of high-voltage and high-power IGBT modules is accelerating. It currently has production capacity, but there is still a certain gap in product performance compared with leading international companies.
Industry analysts at New Thinking said that high-voltage and high-power IGBT modules are developing in the direction of high functional integration, high isolation voltage, high driving power, and high switching frequency, which will further reduce product size and improve product performance. Whether from the perspective of downstream application markets or technology upgrade space, the high-voltage and high-power IGBT module industry has great room for development in the future. In the long term, the market prospects for high-voltage and high-power IGBT modules are good, and Chinese companies need to speed up technological upgrading to achieve import substitution of high-end products.
