本文旨在研製一單相低功率太陽光電能能量轉換系統，將太陽能板所產生的直流電力轉換成交流電力輸出。轉換器的功率電路由推挽式轉換器與全橋式變流器兩級電路串接而成，可使太陽能電池模組的組裝更具彈性。本系統可操作在市電併聯模式或獨立運轉模式，在市電併聯運轉模式下並可隨著不同的日照強度，調整變流器的輸出電流控制訊號，使太陽能板能夠運轉在最大功率點。最後實際製作一套150W之轉換系統雛形，並且由模擬與實測結果互相比較，以驗證本文所提系統之可行性。

The design and implementation of a small-scale solar energy conversion system is presented in this thesis. The power circuit of the PV inverter is composed of a push-pull converter and a full-bridge inverter. The inverter converts DC power generated by photovoltaic cells into AC power. This design allows flexible arrangements of various solar cells modules. The systems can supply loads and feed excess power to the grid with unit power factor when operated under grid-connected mode, or supply loads exclusively by operating in the stand-alone mode. In grid-connected mode, it is controlled to follow the variations of solar panel insolation for achieving maximum power point tracking. A 150W prototype of the conversion system is implemented, simulation and experimental results are provided to verify the performance.
