摘要
机载设备的稳定工作离不开安全可靠的电源系统。文中研究了一种具有自动监测和保护功能的电源系统,详细讨论了智能电源模块的软硬件实现方法。系统是基于DSP处理器SMJ320F240的电源模块,采用1+1冗余供电结构,可实时监测28 V电压、负载电流,进行电源开关阵列(PSA)的通断控制,并与CPU模块进行通讯。
The stability of the airborne equipment relies on the safe and reliable power supply system. In this paper, a power system with automatic monitoring and protecting function is studied, and the intelligent power module＇s hardware and software implementation method is discussed in detail. Based on DSP processor SMJ320F240, power module structure of 1 ＋ 1 redundant power supply is adopted, which can realize the current voltage detection, input overvoltage surge suppression, input peak surge suppression and other intelligent management functions.
