摘　　要：针对目前卫星电源系统动态参数的测试具有自动化水平低、准确度低、数据记录和分析能力差等缺点,设计了一套电源动态参数测试系统,该系统利用太阳能电池模拟器、电子负载模拟卫星在轨运行时太阳帆板的输出和载荷的功耗变化,配合高速采集卡研制动态特性测量单元等模块,组建卫星电源系统及动态参数测试系统并对其进行了测试,母线电压测量及纹波测量结果的相对不确定度均小于0.1%。In view of the disadvantages of low automation level,low accuracy,poor data recording and analysis ability in the test of dynamic parameters of satellite power supply system,a set of dynamic parameters test system of power supply was designed.The solar cell simulator and electronic load were used to simulate the output of solar sail and the power consumption change of load when the satellite is in orbit,and high-speed acquisition card was cooperated with to develop dynamic characteristics measurement unit and other modules,the power supply system and dynamic parameter test system ofthe satellite were built and tested.The relative uncertainty of bus voltage measurement and ripple measurement results were less than 0.1%.
