| Abstract: | 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. |
