The m-SAS Photovoltaic Array Simulator is designed for testing today’s complex small satellites with MPPT regulation topology.
Satellites in Earth orbit and other spacecraft within Jupiter's orbit (or any planet) typically rely on photovoltaic arrays, supplemented by batteries, as their main power sources. These arrays, composed of multiple solar cells, supply power to satellites and have distinct current-voltage (I-V) characteristics. The power output fluctuates based on environmental factors (e.g., temperature, irradiation) and operational conditions (e.g., eclipse, spin).
To ensure reliable performance over years or decades, satellites undergo extensive ground testing. This testing necessitates a solar array simulator (SAS) capable of replicating a photovoltaic array under various illumination conditions and the loads experienced during orbital operation.
