Expanded Information:
1, optimize the use of electrical energy
Through the power electronic technology of electrical energy processing, the use of electrical energy to achieve reasonable, efficient and economical, to achieve the optimal use of electrical energy. For example, in terms of power saving, for fans and pumps, electric traction, rolling mill smelting, light industry paper, industrial kilns, induction heating, welding, chemical industry, electrolysis and other 14 aspects of the survey, the total amount of potential power saving is equivalent to 16% of the national power generation in 1990, so the promotion of the application of power electronic technology is a strategic measure for energy saving, general energy-saving effect of up to 10% -40%, our country has been a number of installations Included in the promotion and application of energy-saving projects.
2, the transformation of traditional industries and the development of mechatronics and other emerging industries.
According to the prediction of developed countries, in the future, there will be 95% of electric energy to be processed by power electronic technology and then used, that is, industry and civil use of various electromechanical equipment, there are 95% of the power electronics industry related to, in particular, power electronic technology is a weak control of the strong media, is an electromechanical equipment and computers, an important interface between the traditional and emerging industries to adopt the microelectronics technology to create conditions , which becomes the guarantee and foundation for the role of computers.
3,? Power electronics technology, high-frequency and frequency conversion technology development, will enable electromechanical equipment to break through the industrial frequency tradition, to the direction of high-frequency development. Achieve optimal efficiency, will enable electromechanical equipment to reduce the size of several times, dozens of times, the response speed to high-speed, and can adapt to any reference signal, to achieve no noise and has a new function and use.
4, the progress of power electronics intelligence, to a certain extent, the information processing and power processing in one, so that the integration of microelectronics and power electronics technology, its development is likely to cause a major reform of electronic technology.
