"Spacecraft Power Systems presents comprehensive coverage of the fundamentals, design-trades, components, controls, and operations of spacecraft power systems. It includes emerging high voltage systems for in-space propulsion for interplanetary travels. With new and updated chapters, sections, and discussions, the second edition covers current high-voltage MW-scale electric propulsion, updated PV and battery systems, spacecraft power components, power electronics, and their architectures and operations. The book explores the latest in spacecraft design processes and trades, controls, operations, and protection. The book is intended for senior undergraduate and graduate mechanical, aerospace, and electrical engineering students taking courses in Space Systems, Space Engineering, and Spacecraft Power Systems, as well as practicing aerospace and power engineers and managers who are designing, developing, and operating spacecraft power systems"--
