本論文旨在利用現場可規劃邏輯閘陣列FPGA(Field Programmable Gate Array)作為控制器，設計一單級式最大功率追蹤換流器，將太陽能電池所獲得之直流電壓，經全橋式換流器轉換成交流電源。藉由單級架構提昇轉換效率，並利用FPGA完成最大功率追蹤控制策略。 本文首先探討太陽能電池的工作特性及最大功率追蹤(Maximum Power Point Tracking, MPPT)技術，其次將依序說明單相式換流器之電路原理與電路設計考量及正弦脈波寬度調變技術之操作原理，最後以FPGA為控制器實做一單級式最大功率追蹤換流器以驗證本論文之理論及設計的正確性。

The design and implementation of a FPGA-based single stage MPPT inverter is proposed in this thesis. The full-bridge inverter converts DC power generated by photovoltaic cells into AC power. Single stage full-bridge inverter is used to increase the efficiency of the system. A FPGA controller is implemented to realize MPPT algorithm. First, the feature of the photovoltaic cells and MPPT algorithm are discussed. Then the operation principles, circuit considerations of the full-bridge inverter and sinusoidal pulse width modulation are studied. Finally, experimental results are performed to verify the theoretical discussion and design procedure of a single stage MPPT inverter based on FPGA controller.
