摘要/Abstract

摘要： 供配电系统是星载偏振成像仪电子学系统的重要组成部分，它不仅要满足将卫星平台提供的一次电源转换成载荷所需的各种二次电源的功能需求，同时还需要满足载荷在轨运行时的高可靠性和长寿命要求。电子元器件的应力分析法是分析电子系统可靠性的一种重要方法，基于应力分析法并根据GJB/Z 299C-2006《电子设备可靠性预计手册》，对星载偏振成像仪供配电系统各组成部件的电子元器件进行失效率计算，并结合系统结构框图对系统的可靠度进行分析。分析结果表明，采用冷贮备的冗余设计方式可以明显提高系统的可靠度。

Abstract: As an important part of the spaceborne directional polarization camera, the power supply and distribution system not only needs to meet the functional requirements of converting the primary power provided by the satellite platform into the various secondary power supplies required for the loads, but also needs to meet the requirements of high reliability and long life when the loads are on orbit. The stress analysis procedure is an important method for analyzing the reliability of electronic systems. Based on the stress analysis procedure and according to GJB/Z 299C-2006 "Electronic Equipment Reliability Prediction Manual", the failure rate calculation of the electronic components in the power supply and distribution system of the directional polarization camera is carried out, and the reliability of the power supply and distribution system is analyzed by combining the structural block diagram of the system. The analysis results show that the redundancy design of cold standby can significantly improve the reliability of the system.

Key words: directional polarization camera, power supply and distribution system, reliability, stress analysis procedure, failure rate calculation
