The EXOMARS Trace Gas Orbiter Electrical Power Subsystem
This paper presents the Electrical power Subsystem (EPS) of the ExoMars Trace Gas Orbiter (TGO) and in particular how the power generation, conditioning and distribution electronics have been designed and developed. It provides a detailed description of the power equipment’s, of the Photovoltaic Assembly (PVA) and, in particular, how the extreme environmental and operative requirements of the mission are met. The design characteristics of the EPS elements are described and a summary of the main performances is given, including the results of the coupling test performed between the power conditioning and the battery. It will be also shown how the design of the power conditioning and distribution electronics has taken advantage of the Selex ES heritage on Power Management and Distribution (PMD) for scientific platforms.
