Innovation and development of power supply technology [Copy link]

Human economic activities have entered the industrial economy era and are entering a period of rapid development of high-tech industries. The power supply is a power supply device located between the mains (single-phase or three-phase) and the load, providing high-quality electric energy to the load, and is the foundation of industry.

　　Power supply technology is a multidisciplinary cross-cutting technology that uses power semiconductor devices and integrates power conversion technology, modern electronic technology, and automatic control technology. With the development of science and technology, power supply technology is closely related to many fields such as modern control theory, material science, electrical engineering, and microelectronics technology. At present, power supply technology has gradually developed into a comprehensive technical discipline with multidisciplinary mutual penetration. It plays a key role in providing high-quality, high-efficiency, and high-reliability power supplies for modern communications, electronic instruments, computers, industrial automation, power engineering, national defense, and some high-tech technologies.

　　Many contemporary high-tech technologies are related to the transformation and control of basic parameters of the city power supply, such as voltage, current, frequency, phase and waveform. Power supply technology can achieve precise control and efficient processing of these parameters, especially the frequency conversion of high-power electric energy, thus providing strong support for the development of many high-tech technologies. Therefore, power supply technology is not only a high-tech itself, but also the basis for the development of many other high-tech technologies. The further development of power supply technology and its industry will surely provide an important means for significantly saving electric energy, reducing material consumption and improving production efficiency, and will have a profound impact on modern production and modern life.

　　Power supply has now become a very important basic technology and industry. From daily life to the most cutting-edge technology, it is inseparable from the participation and support of power supply technology. Power supply technology has also developed step by step in this environment.

2 Innovation of power supply technology

The transistor was invented at the end of 1947, and less than a decade later, the silicon-controlled rectifier (SCR, now called thyristor) was invented based on the gradual maturity of the transistor, thus opening the prelude to the rapid development of power supply technology. Over the past half century, the development of power supply technology has continued to innovate.
