摘要
介绍一种新颖的通信电源后备系统,该系统能在恶劣环境下可靠工作,在正常供电情况下以理想的充电曲线向电瓶充电,当交流供电不正常时自动切换到电瓶供电状态。系统主要由UC2906,VI-26L-CU和外围电路组成,目前该系统已经应用于直放机电源中,长期工作运行表明该系统可靠性高,性能优良。
This paper presents a new kind of electric source power supply preparatory system of correspondence. the system adaptability to complicated situation. In normal condition, the battery package charged according to ideal chargecurve. Otherwise, Automatically switch to batterypackage supply state. The system is mainly made of UC2906,VI26LCU and peripheral electric routes, the system has been applied in the power of directness machine and in long run use, the result has proved high reliable and good functional.
