本論文提出一以平均電流模式控制為基礎之最大功率追蹤光伏系統。現今大部分之光伏系統係以昂貴的數位控制電路達成最大功率追蹤。因此，此新穎之最大功率追蹤電路係以類比電路取代現有之數位電路，以增進經濟效益。
　　藉由利用太陽能板之輸出特性，以平均電流模式控制法將可調節太陽能板之輸出電流和功率。特別地，本論文所提出之最大功率追蹤電路可以採用簡單經濟之功因修正(PFC)類比控制晶片(IC)實現。
　　再者，本最大功率追蹤電路包含溫度補償電路，以確保在各操作溫度之環境下，皆能具有最大功率追蹤功能。最後，實做一個具最大功率追蹤之光伏系統雛型電路，以驗證本論文所提出之理論。

　　This thesis presents a novel maximum power point tracking (MPPT) scheme for the photovoltaic system. Most conventional MPPT technologies in the photovoltaic system are implemented with digital control circuit, which causes the cost-consuming issue. Therefore, the proposed MPPT photovoltaic system can be implemented with analog control circuit, which is substituted for the digital control circuit.
　　By associating the output electrical characteristics of solar cell module, the proposed MPPT control scheme adjusts the photovoltaic current and power with average current-mode control (ACMC) scheme. Especially, this proposed MPPT control scheme with the ACMC can be simply and cost-effectively implemented with the present power-factor-correction (PFC) control ICs available on the market.
Furthermore, with considering the temperature effect on the electronic characteristics of the solar cell module, the temperature compensation circuit is associated with the MPPT circuit to ensure the claimed function even at different temperature conditions.
　　Finally, the prototype circuit of the 85W photovoltaic system with the proposed MPPT control scheme is built in order to validate the claimed MPPT function.
