本論文主要提出一種以數位信號控制完成的隔離式太陽能逆變器,其具有高功率高效率之優點。研究內容以降壓型電流饋入全橋電路結合極性選擇器來實現一種具有最大功率追蹤(MPPT)技術的DC/AC轉換器。
本架構應用在高功率太陽能轉換場合,以簡單的電路架構可實現高準確度的最大功率追蹤、良好的輸出調節以及高效率,透過使用數位信號處理(DSP)晶片來實現弦波輸出與最大功率追蹤功能。
本論文將詳細討論與分析此高功率太陽能逆變器的操作原理和參數設計,最後實現一台輸入150/300 VDC、輸出 110/220 VAC、輸出功率2 kW的太陽能逆變器,以驗證本論文的可行性。
This thesis mainly presents a high-power and high-efficiency digital controlled isolated solar inverter. A buck-current-fed full-bridge circuit combined with a polarity selector is studied to realize the DC/AC converter with maximum power point tracking (MPPT).
High efficiency, simple circuit topology, high MPPT accuracy and good output regulation can be achieved for high-power solar energy conversion applications. A digital signal processing (DSP) chip is used to realize the sinusoidal output waveform and MPPT function.
The operating principles and design considerations for the proposed high-power solar inverter are analyzed and discussed in details. A 2kW laboratory prototype with 150/300 VDC input/ 110/220 VAC output is implemented and tested to verify the feasibility of the proposed scheme.
