The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Power System Design, Analysis, and Power Electronics Implementation on Generic Nanosatellite Bus (GNB) SpacecraftBonin, Grant 16 February 2010 (has links)
The development of a multi-mission small spacecraft power system is described. This system has been designed for the University of Toronto Space Flight Laboratory Generic Nanosatellite Bus (GNB), an approximately 20cm cubical spacecraft with no deployed solar arrays. The GNB is inherently power-generation limited, and consequently, all available power must be utilized with maximum efficiency. This efficiency is achieved using an unconventional parallel-regulated architecture with Peak Power Tracking (PPT) functionality, and is shown to be the PPT design of highest efficiency for spacecraft of this class. In support of this design, a novel spacecraft power simulation suite has been developed, enabling parametric satellite power analysis with high fidelity. Finally, a unique variation on peak power tracking---referred to as peak current tracking---is described. This method is shown to reduce battery depth-of-discharge by as much as 20% over baseline architectures, and furthermore exhibits beneficial emergent behaviour for battery charge management.
