本論文提出應用於串聯太陽能板雙向部分功率調節之最大功率追蹤(Maximum Power Point Tracking, MPPT)方法。每片太陽能板配置一雙向返馳式轉換器，將電流抽出或匯合太陽能板電流以形成主導電流，使每塊太陽能板操作在各自的最大功率點(Maximum Power Point, MPP)。串聯之太陽能板提供大部分能量至負載，轉換器僅處理少部分能量，且當光照強度有較大差異時，太陽能板不會被短路，造成輸出電壓劇烈變動。

主導電流可設定在特定太陽能板的最大功率點上，該太陽能板所連接的返馳式轉換器無需啟動，使所有經返馳式轉換器調節的功率最小，從而輸出系統最大功率。本研究建置由三塊太陽能板串聯並各自搭配雙向返馳式轉換器所組成的實驗系統。實驗結果證明所提出的MPPT方法在不同的遮陰情況下之可行性與效果。

This thesis proposes a maximum power point tracking (MPPT) scheme with bidirectional partial power regulation for a solar power system with a number of photovoltaic (PV) panels connected in series. To operate all PV panels at their maximum power points (MPPs), each panel is attached by a bidirectional flyback converter to add or subtract an adequate current to the PV current to flow into an identical series current. As a result, only a part of power is processed by the associated converters, most power is directly supplied to the load from the series PV panels. With such a configuration, none of the PV panels will be short-circuited, and hence no drastic change will happen on the output voltage, even though they are under extensively different irradiances.

The system maximum power can be realized by allocating the identical series current at a specific MPP, at which, the associated flyback converters need not be activated, and at the same time the total processed power via the flyback converters can be minimized. A laboratory system composed of three PV panels with the associated bidirectional flyback converters is set up. Experimental results have demonstrated the feasibility and effectiveness of the proposed MPPT scheme under various partially shaded cases.
