太陽能晶片技術的快速發展，使得太陽光電系統已有顯著的進步。太陽能有著潔淨發電的優點，然而太陽能板在不同照度、負載、溫度下有寬範圍的電壓變動，通常必須使用最大功率追蹤控制來取得最大功率輸出。串聯連接的太陽能板在其中一塊太陽能板特性退化時，效率會嚴重劣化。而且，太陽能板也常因不同面板方向及遮蔽效應等操作在不匹配條件下。本論文搭配擾動觀察最大功率追蹤功能的模組整合型轉換器，採用高昇壓比直流/直流轉換器設計擷取每一塊太陽能板上的最大功率，並提供高電壓直流匯流排予後級直流/交流換流器使用。數位控制方面採用TI TMS320X2808 DSP晶片。而本實驗的電力來源是利用Agilent E4360 太陽能模擬器來實現，實驗雛型的呈現以及測試的結果驗證了最大功率轉移追蹤模組的可行性。

The rapid advances in solar cell technology have enabled the significant developments in photovoltaic power system. The solar power has the advantage of clean electricity generation. However, the solar panels present wide range of voltage variations under different solar irradiation, load and temperature conditions. A maximum power point tracking (MPPT) control is usually applied to extract maximum power from the photovoltaic system. Efficiency performance of series-connected solar panels is seriously deteriorated by an individual that has worse efficiency characteristics. The PV panels often work in mismatching conditions due to different panel orientations and shadowing effects. This thesis studied a module-integrated converter with P&O MPPT function. A high step-up voltage ratio DC/DC converter was designed to release the maximum power of each PV panel and provide a high voltage DC bus for the post-stage DC/AC inverter. A DSP chip TI TMS320X2808 was adopted to realize the digital controller. An Agilent E4360 solar simulator was used as the power source in experiments. The experimental results for a laboratory prototype were implemented and tested to verify the feasibility of the studied MPPT prototype module.
