| Summary: | 碩士 === 國立虎尾科技大學 === 航空與電子科技研究所 === 97 === This thesis presents the design and implementation of a new maximum power point tracking (MPPT) controller for PV-Power micro-satellite systems. The conventional perturbation and observation MPPT method is modified with a grey prediction method to achieve the optimal perturbation value and improve the efficacy of the PV system in this thesis. In addition, the electrical power system (EPS) of the micro-satellite generates, stores, conditions, and distributes power within the specified voltage and power to all bus and payload equipment. Therefore, the analysis and design of the proposed MPPT controller, DC/DC converters, battery charger and sensors are proposed in the thesis. Simulated and measured results from a prototype have confirmed the effectiveness and feasibility of the proposed approach.
