适合通信系统的低压、大电流电源的现状及展望

Present State and Perspectives of Low Voltage and High Current Communication Power Supply

本文主要介绍通信系统中低电压大电流电源设计所面临的稳压、散热、输入噪声和成本等方面的问题,分析多相技术、板上电源、同步整流和次级控制等新技术,并给出了一种低电压、大电流电源的设计实例。

In this paper, the severe challenge facing with voltage stabilization, heat dissipation, import noise,cost and so on in the designing of low voltage and high current communication power supply is introduced briefly, the new technology, such as muhiphase technology,on board supply, synchronous rectification,and secondary control are discussed in detail. Finally, a design example of low voltage and high current communication power supply is presented.
