【 摘 要 】

Solar energy offers a large potential as a source of energy and in light of financialand ethical reasons, people are looking to harvest it for their energy needs. Theconversion of solar energy to electricity is performed by solar cells. There exists anoperating point associated with solar cells at which the power generated is maximized atany given point in time. A maximum power point tracker (MPPT) is required to track thismaximum power operating point (MPOP). A wide range of systems exists to meet thispurpose. This thesis explores the use of a single-phase controlled rectifier, withback stepping control to track the maximum power from a string of solar arrays. Thiscontroller tracks the MPOP using a circuit topology that has been under investigationwithin the literature and was simulated using MA TLAB/Simulink. Simulation resultsshowed that the designed converter and control strategy could transfer power from astring of solar arrays to the grid by efficiently tracking the MPOP.
