Abstract：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%.
