摘　　要：该文介绍了一种用于火箭试验弹服役系统供电的弹载电源系统。该电源系统以MSP430微控制器作为控制核心单元,结合电源控制器芯片LTC4416,实现电源系统锂电池组与地面电源供电方式的可控转换。该系统具备多路功率电源输出,并具有CAN总线通信功能,可实现各路电源电压的实时监测、锂电池组的状态查询及充电控制等多种测控功能。经测试,此电源系统各项功能正常,可稳定工作30 min以上。This paper introduced a rocket-borne power supply system for service devices of experimental rocket. This power supply system consist of a control unit based on MSP430 series MCU. By employing dual powerpath controller LTC4416,the controllable switching between ground power and interior power is well realized in the system. The pre- sented system cloud afford multiple channel power supply output. It could also achieve real time output voltage mon- itoring,lithium cells status inquiring as well as steerable battery charging by integrating CAN-bus communication module in the system. The functionality and 30 minutes working endurance of this proposed power supply system has been successfully verified through experiments.
