Top-down approach to EPS architecture for spacecraft electrical power systems Filling a gap in the existing literature, Spacecraft Electrical Energy Systems guides readers through the design and development of Electrical Power Systems (EPS) for spacecraft using a top-down approach. The book opens by introducing the function of EPS for spacecraft and giving an overview of the different types of EPS technologies available. It then takes readers through the detailed design and development parameters for EPS, with a focus on requirements and standards from the ECSS and NASA, enabling readers to make more informed decisions as they work on real-world spacecraft projects. It explains the functionality of all common types of spacecraft power bus technologies and compares their advantages and disadvantages. Spacecraft Electrical Energy Systems also discusses: Spacecraft Electrical Energy Systems delivers important cutting-edge knowledge for professional aerospace engineers, as well as electrical engineers working within the space industry and early-career engineers who are new to the field. The book can also be used by students and instructors in graduate-level specialty courses.
