低轨道微小卫星电源系统研究

Research of electrical power subsystem for the low earth orbit minisatellite

低轨道微小卫星目前应用广泛,其体积小、质量轻、成本低、应用最新技术等特点使其具有广阔的发展空间。电源系统是卫星的几大核心系统之一,结合目前电源系统特点对低轨道微小卫星电源系统开展研究分析,提出了一种典型的系统拓扑设计方案,并结合工程化应用开展了可靠性、安全性分析。

The minisatellite is widely applied with the advantages of small size, low volume and costs in low earth orbit （LEO）, and with the new advanced technologies for greater potential of future development. The electrical power subsystem （ EPSS ）is one of the key subsystem of satellite and provide power to all subsystems during all mission phases. Some characteristics of projects researching presently about the EPSS of the minisatellite in LEO were summarized and a typical system topology project was submitted. A detailed simulation including reliability and safety according to the research of actual projects was performed.
