The large-signal trajectories of the system's operating point are analyzed employing qualitative graphical representation. The analyses are verified through simulation using EASY5 software. Small-signal dynamic characteristics of spacecraft battery charge converter systems are analyzed to facilitate the design of control loop for optimum performance and stability. Control-loop designs for the charge converters in bus voltage regulation mode, charge current regulation mode, and peak power tracking mode are discussed.x, 244 leavesBTDapplication/pdfenIn CopyrightLD5655.V856 1991.K57Space vehicles -- Batteries -- ResearchDissertationhttp://scholar.lib.vt.edu/theses/available/etd-05222007-091329/
