由於近年來能源短缺的問題,各國已經開始重視替代能源的發展,而太陽光電能具環保且容易取得的優點,使得科技業積極地開發更高效能的太陽能電池以及太陽能相關產品。
本論文個別設計太陽能地最大功率追蹤器、單相全橋換流器與蓄電池的充放電電路,並整合起來完成獨立型的太陽能供電系統。所使用的最大功率追蹤演算法為增量電導法,比起擾動觀察法有更佳的準確度。利用單相全橋換流器可以將最大功率追蹤器的輸出直流電轉換成110Vrms、60Hz的正弦波交流電,可供給一般的家電產品使用。而電池的充放電電路則可以調節太陽能供電系統的能量平衡。經由實作電路的實驗數據與波形,可以證明太陽能供電系統在啟動蓄電池充放電電路調節系統能量時,最大功率追蹤器依然可以正常動作,且換流器輸出依然可維持在110Vrms交流電,達到供電系統之穩定。
Due to problem of energy shortages in recent yeats. Countries have begun to attach importance to the issue of alternative energy sources. The solar photovoltaic energy have advantages of environmental protection and easy access, making the industry develop higher performance of solar cells and solar related products.
In this paper. It desing the maximum power tracking of solar energy, and single-phase full-bridge inverter and the battery charge and discharge circuit, and combination of a stand-along photovoltaic system. Using the maximum power tracking algorithm for the incremental conductance method, compared to the disturbance observation better accuracy. The single-phase full-bridge inverter can use the output DC power of maiximum power tracker, and convert to AC 110Vrms, 60Hz sine wave power to household electrical production. The battery charge-discharge circuit can adjust the energy balance of the photovoltaic system. Through the data and waveform of experiment. It can prove the maximum power tracking can still action at battery chare-discharge circuit is action in the photovoltaic system, and the inverter output is still maintained at 110Vrms AC power and system can keep stability.
