SOLAR EMULATOR AND SIMULATOR DESIGN FOR CUBESATS

摘要

A highly efficient, redundant electrical power system is developed in Istanbul Technical University (ITU) SpaceSystems Design and Testing Laboratory (SSDTL). A Hardware-in-the-loop (HIL) simulation platform is designedfor testing, calibration and qualification procedures of the power system. The system is based on aMATLAB/Simulink model of space qualified solar cells. A DC/DC converter generates required power for anygiven load depending on the solar cell model. An interface drives the converter by the information from the solar cellmodel. The system is connected to developed power system, in order to measure its performance. This paperexplains the methods, trade-offs and the results of the project.
