Abstract:	由於太陽能電池輸出功率會隨著太陽光照度與溫度的改變而有所變化，使得太陽能電池並非隨時都工作在最大功率點上，因此浪費了許多能量，而本研究的目的為設計一最大功率追蹤控制器控制太陽能電池，使太陽能電池能夠適應外在因素的改變一直保有最佳功率輸出，此即是本研究的最大目的。本研究主要是由dsPIC30F4011數位訊號處理器作為控制核心，透過dsPIC30F4011的10 bit A/D轉換模組量測太陽能電池輸出電壓與輸出電流，然後經由增量電導法與升壓型電路轉換器改變阻抗，使得太陽能電池輸出最大功率，並以Labview人機介面紀錄太陽能電池輸出資訊。Due to the output power of solar cell varies with illumination and temperture，the solar cell uaually not operate on the maximum power point(MPPT)，and then wasted a lot of energy。The study focuse on implementation of maximum power tracker ，which can improve the output power of solar cell under varing illumination and temperature。The study is based on dsPIC30F4011 digital signal processor，we measure the voltage and the current of solar cell by the dsPIC30F4011 10- bit A/D converter，then though the incremental conductance method and boost converter to change the output impedance of solar cell，controll the solar cell have the maximum outpour power。And using the Labview human-machine interface to record the outpour data of solar cell。
