小型化直流电源发展动态

The Development of DC/DC Converters

随着电子整机向小型化、轻量化方向的发展，对整机所用的直流稳压电源也提出了小型化的要求。本文叙述了国外ＤＣ／ＤＣ变换器的研究与开发情况，介绍了国内发展集成化直流稳压电源的现状，分析了国内市场对ＤＣ／ＤＣ变换器的需求。对国内外在该领域的技术水平进行了比较，提出了发展我国小型化直流电源的对策。

The development ofDC/DC converters is described.The R&D of the device abroad is reviewed.The research efforts and achievements inChina in this field are introduced.Based on the analysis of the market demand on the DC/DC converter and the actual technical level,propos-als are put forward for the development of China's miniturized DC power units.
