1. The development history of switching power supply


Switching power supply has a history of more than 70 years. With the technological change and innovation of the industry, switching power supply products and types continue to develop and enrich. At present, the switching power supply industry is in a mature stage of development.


The research and application of switching power supply began in the 1950s. In 1955, the American GH.Roger invented the self-excited oscillation push-pull transistor single transformer DC converter, the first pulse width modulation (PWM) control, laying a theoretical foundation for the development of switching power supply. In the 1960s, switching power supply technology was basically formed. The first generation of civil standardized switching power supply was born in the 1970s, and in the mid-1980s, there was a global standard of switching power supply. In the 1990s, with the continuous development of upstream components and key technologies of power electronics, switching power supply technology has achieved rapid development, rapidly growing into an important basic product in the electronics industry. In the 21st century, the industry has entered a mature stage of development, with more diversified products and more complete functions. With the development of digital circuit technology, computer control technology and its application in power electronics technology, high frequency switching power supply has entered the era of digital power supply.


Switching power supply has the advantages of miniaturization, light weight and high conversion efficiency. With the continuous development of electronic technology and the continuous improvement of design, switching power supply has a long-term advantage in reducing energy consumption, and meets the safety, electromagnetic compatibility, environmental protection and other certification requirements of electronic products, so as to quickly become the mainstream power products.
