隨著人們使用行動裝置時間持續增長，行動電源也漸漸成了身邊的必要配件之一；然而，手機使用時間不斷攀升的同時，就算具備行動電源也難防在緊急時後遭遇電量不足之情形。本論文提出利用太陽能板結合行動電源，無時無刻儲蓄電量，不僅能增加行動電源之功能性、生活便利性外，更對未來行動裝置發展帶來改變。此外，為了避免太陽光照度不足導致無法充電的情況，同時提出以手持式發電機作為電力來源的替代方案。本論文所研製之綠能行動電源主要可分為：升壓轉換器、返馳式轉換器以及充電控制系統三個部分。結果顯示，綠能發電能夠藉由升壓轉換器來增加其驅動充電控制系統充電之工作範圍，由原先的4.5 V~5V增加至3V~5V；電池經由返馳式轉換器後能夠利用市電充電；充電控制系統之效率皆達90%以上。最後，由整體架構的實測證實綠能充電的可行性；其單組發電時轉換效率最高能夠達到79.51%；若為兩組同時輸入時則其最高轉換效率提升至80.19%。 When people spend more time using their smart phone, the power banks have gradually became one of the standard accessories today. However, because the mobile usage time continually increases, the power bank cannot avoid the low battery condition even on the emergency situation. This thesis proposes a power bank, which can charge the battery from the solar power thus the power bank can charge the battery anytime. It not only increases the function of the power bank, but also makes the life easier than before. Furthermore, it makes some breakthrough for future mobile devices. Moreover, to prevent the power bank cannot charge under the dim environment, this thesis also proposes handheld generator to charge the power bank. The power bank proposed from this thesis consists of three parts, which are the boost converter, Flyback converter and the charge control system. The result shows that the green generator can increase the operation range from 4.5V-5V to 3V-5V by using the voltage converter. The battery can fully charge through the Flyback converter from the standard AC charge source. The efficiency of the charge control system is over ninety percent. Finally, the experimental result shows the feasibility of the green charge. The efficiency of the converter can achieve 79.51 percent under the single input condition. The efficiency of the converter can improve to 80.19 percent under the double input condition.
