3.3.9.3 SAS MODE
The Chroma 62000H Series DC Power Supply with Solar Array Simulation is not only able to
simulate the Solar Cell curve using the Solar Array Simulation Soft Panel but it also has a
built-in model to provide a solar cell curve simulation function called SAS Mode. See Britton,
Lunscher, and Tanju, "A 9 KW High-Performance Solar Array Simulator", Proceedings of the
European Space Power Conference, August 1993 (ESA WPP-054, August 1993) for the
built-in model. The model formula discussed in the thesis is described below.
