摘要

有鑒於環保意識的抬頭及石化能源逐漸短缺及其價格也不斷的攀升，因此使用再生能源即是一種趨勢。太陽能即是一種無汙染、無危險及無限量的再生能源。本文將依據太陽電池輸出電壓及電流關係之特性，再配合使用最大功率追蹤法中的增量電導法，來使的太陽電池始終能維持輸出在最大功率點狀態下工作，以達到本文所研究的目的。
本研究是以數位訊號處理器dsPIC30f4011為控制核心。藉由量測太陽電池輸出的電壓及電流，並透過增量電導法的演算後，再對升壓型直流/直流轉換電路中的功率開關電晶體進行切換控制，以實現太陽電池輸出會維持在最大功率點之目的。

In view of the rise of environmental awareness and shortage of fossil energy gradually and continuously rising prices, the use of renewable energy that is a trend. Solar energy is a renewable energy that is pollution-free, risk-free and in-finite. The thesis will be based on the voltage and current of the solar cell . Maximum power point tracking method using the incremental conductance me-thod to make the solar cells will always be able to maintain output at maximum power point mode of operation, so that to achieve the purpose in this study.
The thesis is based on the digital signal processor dsPIC30f4011 for the control of the core. By measuring the output voltage and current of the solar cell, and through the incremental conductance method of calculation, And then con-trol the power transistor in the boost converter circuit to achieve the solar cell output will remain at maximum power point.
