太陽能光電能源轉換器之研製

本論文提出太陽能光電系統之電池組充電器，其功用為調節太陽能板輸出的直流電力，並對電池組進行充電控制。由於太陽能光電板之輸出功率受大氣環境的變動所影響，充電器必須對太陽能光電板進行最大功率追蹤，以獲得太陽能光電板之最大功率輸出。在充電的過程中，充電器必須判斷太陽能光電板的輸出功率大小與電池組的充電狀態來變換充電模式，以防止電池發生過度充電之情況。本文首先探討與分析各種太陽能板之最大功率追蹤方法與鉛酸電池之充電方法，根據分析的結果建立適合本系統之充電策略，並設計出以微處理器為控制核心，結合升壓式與返馳式轉換器為主電路架構的電池組充電器。經由電腦模擬與實作結果之相互驗證，可知本文所研製的充電器能依據太陽能光電板輸出功率與電池組的充電狀態，對電池組進行最大功率、ReflexTM與定電壓三種充電模式之控制。

This paper presents the solar system's battery charger, function to adjust the solar panel's DC power output and battery charge control , as the output power of solar panels by the impact of changes in atmospheric environment charger must be solar panels for maximum power tracking,maximum power output get the solar panel. In the process of charging, the charger must determine the output power of solar panels the size of the battery pack state of charge to transform charge mode to prevent overcharging of the battery case this discussion and analysis of the first solar panels of the maximum power tracking method , and method of charging lead-acid batteries .According to results of the analysis to establish strategies for the system of charging,and design a microprocessor to control the core, combined with the step-up and flyback converter-based battery charger circuit architecture By the results of computer simulation and implementation of mutual authentication, we can see the charger can be developed in this paper based on solar panels output power and battery charging status, battery pack maximum power, ReflexTM and constant voltage control of three charge modes.
