摘　　要：在分析了卫星在转移轨道阶段的用电需求,依据星箭接口通用的设计原则,从卫星的供电裕度、供电品质、供电安全等方面,对上面级与卫星之间的接口进行匹配性研究,并对一箭双星发射任务,上面级对卫星供电、卫星直接入轨的应用情况进行总结。结果表明,上面级供电双星同时工作的状态下母线电压的稳定性和上面级加断电过程中双星母线的瞬态特性,满足卫星使用要求。这可为其他一箭多星上面级直接入轨卫星的星箭供电接口设计提供参考。The power supply requirements of the satellite in the phase of orbit transfer were analyzed in this paper.According to the general design principle of the interface between satellite and rocket,from the several aspects of the power supply margin,power supply quality,power supply safety,the matching research on the interface between the upper stage of rocket and double satellites was carried out.And the application of power supply for the direct entry into the orbit of the upper stage of rocket satellite attached with two satellites was summarized.The results show that the stability of the bus voltage and the transient characteristics of the bus in the process of power on and power off of the upper stage can meet the requirements of the satellite operation.The research can also provide a reference for the design of the power supply interface of the rocket which is launching multi-satellite.
