摘要

本論文主要利用超級電容當作獨立充電儲能系統，硬體系統不需要連接任何外部電源裝置及電池供電，除此之外自充電/自供電電路有自動關閉概念，本論文電路設計概念主要以自主性、低成本和低汙染構想為出發點，本論文採用前饋式充電，可以省略電壓/電流迴授電路，降低整體電路複雜度及成本，由於前饋式充電系統與自充電/自供電電路都與輸出電壓特性有相關，所以本論文會詳細探討兩者系統參數特性，最後本論文也會使用數學模擬及實驗數據來驗證。

This thesis deals with a stand-alone super capacitor charging system. The stand-alone system contains a self starting /self powering circuitry which allows the system power to be turned off while not in use. This proposed system does not use batteries or have a connection to a main power utility; it constitutes a true stand-alone, low maintenance and pollution free system. Additionally, it proposes a feed forward charging scheme to eliminate the needs of using voltage feedback, current feedback, or both, and hence reduces electronic complexity and cost of the charger. A detailed analysis of the feed forward charger, and the self-starting/self power circuitry was carried out to obtain the relationship between the system parameters and the outputs of the system. This thesis also presents simulation results and experimental data to reveal performance of the charger and the self-starting /self powering circuitry.
