摘要

本文旨在建構太陽能變頻器模擬環境以及利用數位訊號處理器為控制核心實現太陽能變頻器，模擬環境之建構包含了太陽能電池及最大功率追蹤技術，使用Matlab/Simulink®模擬軟體來建立。太陽能變頻器採兩級架構，第一級為升壓型DC/DC轉換器，第二級為DC/AC換流器，兩級架構可使用較少的太陽能電池來達到並聯市電的目的，控制電路則以數位訊號處理器TMS320LF2407A為核心，以全數位化設計來實現最大功率追蹤控制。最後以1kW市電併聯型太陽能變頻器實驗結果，驗證最大功率追蹤控制法則，可使太陽能電池在各種環境變化下維持最大之功率輸出。

The objective of this thesis is to build a simulink-based simulation environment and implement a DSP-based full-digital photovoltaic inverter. The simulation environment consists of a solar cell model and a maximum power point tracking model. To yield a good grid-connected performance, the proposed DSP-based photovoltaic inverter is including a full-bridge isolated DC/DC converter and a full-bridge DC/AC inverter. All the control algorithms, such as maximum power point tracking, DC/DC and DC/AC control methodologies, are implemented by software using TI digital signal processor TMS320LF2407. Finally, some experimental results are provided to verify the correctness of the 1kW grid-connected photovoltaic inverter.
