Electronic technology is a newly developed technology, which has three functions!

Page view
Electronic technology is a new technology developed at the end of the 19th century and the beginning of the 20th century. It has the fastest development and the most extensive application in the 20th century. It has become an important symbol of the development of modern science and technology. At the end of the 18th century and the beginning of the 19th century, due to the needs of the development of production, the research on electromagnetic phenomena developed rapidly. In 1895, H.A. Lorentz assumed the existence of electrons. In 1897, J.J. Thompson used experiments to find electrons. In 1904, J.A. Fleming invented the simplest diode (diode or valve) to detect weak radio signals.
In 1906, L.D. forest installed a third electrode (grid) in the diode and invented a triode with amplification function, which is the most important milestone in the early history of electronics. In 1948, several researchers at Bell Laboratories in the United States invented transistors. In 1958, the first sample of integrated circuit appeared in the world. The emergence and application of integrated circuit marks the development of electronic technology to a new stage.
The role of electronic technology
1. Optimize the use of electric energy. Through the processing of power electronic technology, the use of electric energy is reasonable, efficient and economical, and the use of electric energy is optimized.
2. We will transform traditional industries and develop emerging industries such as mechatronics. It creates conditions for traditional industries and emerging industries to adopt microelectronics technology, and becomes the guarantee and foundation for the role of computers.
3. With the development of power electronic technology and frequency conversion technology, electromechanical equipment will break through the tradition of power frequency and develop towards high frequency. To achieve the best working efficiency, the volume of mechanical and electrical equipment will be reduced several times, dozens of times.
