Technical Trends of Switching Power Supply Abroad

Since the 1990s, the development of switching power supply has changed with each passing day. Many new fields and new requirements put forward newer and higher challenges to switching power supply. If we observe from the input and output window of a switching power supply, we can find that the input requirements have become more stringent, and products that do not meet the IEC1000-3-2 standard will be gradually eliminated; The output has derived many special application fields, and the difficulty of research and development has become greater. It is precisely because of these external requirements that the branch technology of two switching power supplies has always become the research topic of power electronics. They are active power factor correction technology and low-voltage high-power DC/DC conversion technology. In addition, due to the improvement of technical performance and requirements, the research of many related technical topics, such as EMI technology, PCBLayout problem, thermal theory analysis, integrated magnetic technology, new capacitor technology, new power device technology, new control, structure and process, is rapidly increasing.
