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.
The Elgar™ mini-Solar Array Simulator meets this need with its 840W power supply, enabling rapid current-voltage (I-V) curve adjustments and quick recovery times, effectively simulating the dynamic environmental conditions in space.
Performance. Reliance. Brilliance.
The Elgar™ mini-Solar Array Simulator is the second addition to the NEXSIM family of space power simulation related products. For small satellite test applications, the m-SAS are specifically designed to emulate the dynamic electrical behavior of a solar array. They offer low output capacitance and high closed loop bandwidth to keep up with the advanced Maximum Power Point Tracking (MPPT) algorithms used in today’s small satellites.
Control via AMETEK m-SAS software and via SCPI commands over Ethernet
The m-SAS is Digital Signal Processor (DSP) controlled and can be operated using AMETEK’s m-SAS software GUI and by sending SCPI commands via the Ethernet through the m-SAS software.
Applications
The m-SAS Photovoltaic Array Simulator is designed for testing today’s complex small satellites with MPPT regulation topology.
ECLIPSE Irradiance Profiles
The Elgar m-SAS irradiance profile allows you to simulate any eclipse scenario. It can be controlled to a very fine degree and real profiles can be entered and run from actual speed to 100 times actual speed for accelerated tests.
