由於太陽能的乾淨環保且與之不盡用之不竭，太陽能系統的應用一直都受全世界所矚目。在太陽能系統中，主要是由兩個部份組成，一是太陽能電池，另一個是電力轉換器，以目前發展現況，太陽能電池的成本高，低效率是影響無法推廣普及的主要原因，而實際應用上，電力轉換器則是整個太陽能系統的核心。
由於太陽能電池的特性，會隨著大氣環境變化而受到影響。本論文提出一應用於操作在不連續模式反馳式轉換器，並以增量電導法則來判斷，利用固定責任週期且變頻的方式，來對太陽能系統作最大功率追蹤，以獲得最大功率轉換。最後，我們實際設計一台光伏能量轉換系統，並利用MATLAB/Simulink模擬軟體分析太陽能系統，以驗證本論文理論及設計。

An incremental conductance (IC) derived MPPT PV stand-along DC bus system by constant-duty variable frequency control is proposed. Fast matching process to executing MPPT PV system is achieved by a simple control programming. The proposed PV system can provide enough energy to load as well as charging the battery with the residual energy. The feasibility is demonstrated by an example of 220W PV stand-along DC bus system with IC MPPT control. The MPPT tracking phenomenon for energy drawing from PV array and supply to load is quite close to the prediction
