摘　　要：描述了小灵通基站电源存在的问题及业界的一般解决方案,并结合《中国电信集团公司小灵通基站直流远供系统技术规范》(暂行)的要求,指明了复用ISDN信号线路进行电力传输时需要解决的关键技术难点:DC-DC电源、复用单元、电力线碰触防护、交直流电源切换单元。重点研究了直流电源、交流电源、基站三者之间的逻辑关系,分析了交直流切换单元的设计思路,阐述了交直流切换单元的设计原理,成功地解决了交流电源和直流电源在不同情况下供电优先级不同的问题。This paper describes the problems of the power supply of PAS （Personal Access System）cell station and the general solutions of the industry.According to the temporary technical specifications of the DC remote supply system of PAS cell station by Chinese telecommunication group,the key technical problems that are the DC-DC power,the multiplex unit,the protection of the touched power line and AC-DC conversion circuit when the multiplex ISDN signal line transmits the elec- tricity.It also focus on the logical relations among DC power,AC power and the cell station,and offers an analysis of the design ideas of the AC-DC conversion circuit.At last,it indicates that the design principles of the AC-DC conversion circuit and successfully solves the problems that whether the alternating current or the direct current supplies the power at first in the different conditions.

关 键 词：小灵通 直流远供 交直流电源切换
