摘　　要：根据SAR卫星有效载荷的脉冲、大功率工作等典型特点及对电源母线稳定度的较高要求,设计了单母线、不调节电源系统方案,建立了电源系统的仿真模型。针对不同负载情况,分别对SAR卫星处于光照区和地影区时,其脉冲大功率电源系统在恒功率负载、负载突减和负载突加的情况进行了仿真分析。仿真结果表明此电源系统稳定,能够满足SAR卫星有效载荷的供电要求。According to pulse and high power characteristic of SAR satellite which requires high stability power busbar, single bus and unregulated power system is designed and a simulation model of power system is established in the paper. The SAR satellite pulse and high power sys- tem is simulated under different load conditions, including the condition of constant power load, sudden load decrease and sudden load increase, respectively. The simulation results display that the power system is stable which can fully meet the requirements of the SAR satellite.
