摘要

本論文之目的在於研製市電併聯型單相太陽能換流器，採用直線近似之最大功率追蹤(Straight-Approach Maximum Power Point Tracker，SA-MPPT)技術，使得太陽能換流器在任何光照下均能工作在最大功率點。本研究中，升壓轉換器吸汲太陽能量並轉換供給換流器，而換流器之電流控制能依SA-MPPT適時地調節輸出電流。本文針對電流控制系統作完整的分析與討論，最後並實際製作一部1kW的太陽能換流器，以驗證性能估測；實驗結果和理論推測相當接近。

The purpose of this thesis is to design and realize a gird-tied single-phase PV inverter. A straight-approach maximum power point tracking (SA-MPPT) is adopted to make the PV inverter work at MPP under different insolation. In this thesis, the boost converter can pump energy from the PV module to the PV inverter, in which the PV inverter can adaptively provide proper current with current control to the power utility according to the guidance of the SA-MPPT. The modeling and analysis of the current control in the inverter are conducted in detail. Finally, a prototype of 1kW PV inverter is designed and implemented to assess the predictions. The experimental result is in feasibility close to the estimation.
