近年來，乾淨無污染的能源如太陽能光伏陣列、風力渦輪機和燃料電池等，已被開發利用於發展可再生能源發電系統。其中，快速進步的太陽能電池技術使得光伏發電系統有了重大的發展。太陽能發電的優點是得以乾淨的發電。但是目前太陽能電池板在不同的太陽照射、負載和溫度條件下，呈現範圍廣泛的電壓變化。故通常在光伏發電系統中使用最大功率追蹤控制技術以擷取最大功率。
本論文研究使用數位訊號控制器做控制的模組化之光伏發電系統。選擇單級全橋式換流器做為電能模組的主要架構來實現最大功率追蹤，以期提供高品質的交流電壓。在本論文中設計與實現具有模組串聯與市網併聯技術之模組化光伏發電系統。最後也驗證本論文之理論與設計的可行性。

Recently, clean energy resources such as photovoltaic arrays, wind turbines or fuel cells have been exploited for developing renewable electric power generation systems. In which, 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. In this thesis, a DSP-based single-stage full-bridge DC/AC inverter with MPPT function is studied for photovoltaic power systems. The developed DC/AC inverter can simultaneously provide high quality AC voltage and achieve MPPT operation with a simple single-stage circuit configuration. Series-connection and grid-connected techniques of the studied single-stage inverter is also designed and implemented for photovoltaic power systems. A laboratory prototype of the studied grid-connected PV system has been built and tested. Experimental results are shown to verify the feasibility of the proposed scheme.
