Design and implementation of a solar array simulator

In order to test the performance and reliability of solar power system of satellites, solar array simulator on earth is needed. Based on the solar cellpsilas mathematic model, this paper designs a practical solar array simulator which can generate the solar cellpsilas I-V character. Since the implemented solar array simulator has the same structure and power as the real system, it can simulate the actual operating of a real solar array to most extent. Experimental results demonstrate the validity of this design which enables the further research on and diagnosis of solar power system.
