Abstract :
A photovoltaic (PV) array simulator consisting of a computer controlled DC power supply producing up to 100 Watts and associated control software was developed to generate real-time current-voltage (I-V) output characteristic curves of space solar power systems (SSPS) under simulated conditions. The control software uses feedback of the output voltage and current to iteratively solve for the correct operating point of any connected load. The main advantage of such a simulator is in its ability to simulate different types and sizes of arrays under any illumination and temperature condition using actual loads, The system will be used to study the short-term and long-term performances of SSPS and to predict end-of-life (EOL) efficiencies. The simulator is a far more cost effective and reliable replacement for flight testing. This research will have future applications in the communication and space industries
