摘　　要：提出了一种MPPT不调节母线电源系统拓扑结构,介绍了其控制策略。分别建立了两域控制模式下太阳电池阵源端与负载端稳态分析的等效电路模型,基于小信号等效分析及状态空间方程特征根求解方法,对系统稳定性进行分析,归纳了提高此类电源系统稳定性设计的方法,此研究结果可为MPPT控制技术在未来空间电源系统中应用提供设计参考。A MPPT（Maximum Power Point Tracking） unregulated bus electrical power system topology for space application and its control strategy are presented. The equivalent circuit mod- els of the solar array sources and the loads in two-domain control modes are built separately. The small-signal equivalent analysis method and solving eigenvalues of state space equations method are adopted to analyze the system stability. Some conclusions on increasing the system stability are obtained, which could be referred for applying the MPPT control technology to the future space electrical power system design.
