Functional-based verification for spacecraft SW: The electrical power subsystem

This paper focuses on verification of spacecraft SW for the electrical power subsystem (EPS) for a particular geostationary satellite. Choosing an appropriate topology is a key point in the process of electrical power subsystem design. Concepts of energy transfer. i.e. Direct Energy Transfer (DET) and Peak Power Tracker (PPT) are discussed. The EPS spacecraft SW verification is based on the functionality of the system and its design. A test software approach is presented in order to verify the spacecraft SW functionality of EPS components.
