The topic of Power Management and Distribution (PMAD) for spacecraft Electrical Power Systems (EPS) is presented. Various PMAD architectures are shown, followed by a discussion of the PMAD elements, and then moving into power distribution and fusing. Design requirements such as power quality and stability are covered, as well as command and telemetry, fault tolerance, and design verification.
