| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 91 === The study and implementation of a DSP-based digital controller for the single-stage three-phase photovoltaic（PV） energy conversion system is proposed in this thesis. The proposed maximum power point tracking strategy allows PV energy conversion system to track the maximum power point rapidly and smoothly. The proposed PV energy conversion system acts as a solar generator on sunny days and as an active power filter under low insolation conditions. In addition, the proposed controller performs maximum power point tracking and also provides power to utility with unity power factor. Moreover, the current controller with single loop is simple and easy to design, as compared with the conventional double loop controller. Finally, experimental results demonstrate the desired performance of the proposed technique.
