摘要
VPX电源标准是目前国际上兼容性最好的军用嵌入式计算机规范,其模块可为机箱中的多个不同功能模块稳定供电。因此设计了一种基于VITA46以及VITA62标准的VPX电源板卡。主要介绍了6U结构电源板卡的设计架构、思路以及所实现的功能,分析了硬件保护、缓启、采集以及DCDC模块电源的电路特性,阐述了软件工作模式、管理流程以及外部结构的设计方式,并通过Maxwell热仿真分析了高温环境下板卡的工作状态,最后通过试验测试了板卡上电时序的稳定性与可靠性,以及带载下负载稳定度与电压稳定度。通过软硬件的研发,所提设计在自主化硬件设计、软件适配等方面积累了一定的经验。
The VPX power standard is currently the most compatible military embedded computer standard internationally,and its modules can stably power multiple different functional modules in the chassis.A VPX power board based on VITA46 and VITA62 standards was designed.The design architecture,ideas,and functions of the 6U structure power supply board were mainly introduced.The circuit characteristics of hardware protection,slow start,acquisition,and DCDC module power supply were analyzed.The software working mode,management process,and external structure design were described.Maxwell thermal simulation was used to analyze the working status of the board in high temperature environments.Finally,the stability and reliability of the board's power on timing were tested through experiments,and load stability and voltage stability under load.Through the research and development of software and hardware,the proposed design has accumulated some experience in terms of autonomous hardware design,software adaptation,and other aspects.
