Abstract

Solar Array Simulator (SAS) is a special kind of DC power supply to simulate the solar array voltage-current characteristics. SAS provides V-I characteristics of solar array for ground testing of complete spacecraft or spacecraft power subsystem. The Solar Array Simulator (SAS) is based on SMPS concept and it gives the switching response to voltage regulator operating at 25 KHz. The SAS is highly efficient and thermal design issues are minimal. This paper describes the complete working principle of the circuit, its simulation analysis and development of SAS.
