Abstract

This paper focuses on evaluating three main design criteria including efficiency, reliability and cost for different topology schemes of Electrical Power Subsystem (EPS) of a satellite in Low Earth Orbit. Selecting an appropriate topology may increase the overall EPS efficiency and extend the lifetime of satellites. In this article, ten basic EPS topologies are studied, evaluated and compared. In order to choose a more efficient and more reliable EPS topology, along with cost considerations, the mentioned parameters would be calculated for each topology separately. In the next step, these topologies can be compared by defining an overall cost function composed of all three criteria.
