中文摘要 本論文首先針對行動電源進行設計,以輕薄短小與節省成本為目標,提出一直流對直流轉換器之升壓與降壓電路,使電壓與電流皆能穩定輸出。由於系統設計在高頻率下工作,使得整體體積相對較小,重量也較輕,且轉換效率也較佳,因此達到輕薄短小之需求。 另外針對應用於直流對直流轉換器中的零件,進行選擇與設計,並利用PWM來控制MOSFET開關,使得輸出電壓能穩定控制,達到節省成本並減少功率消耗的問題。 為了確認準確性與可行性,舉出了八種不同的狀況進行實驗,研究輸出電容與輸出電感間之協調匹配,能節省空間與穩定輸出電壓,以驗證本論文所設計之行動電源,可達到輕薄短小與其可行性。
Abstract In order to reduce the size of power banks and save cost, this paper proposed a DC-DC converter boost and buck circuit to make the output voltage and current could be controlled in the original default values. And because of the high frequency of designed system, the volume could be smaller, weight could be lighter and efficiency higher. This study for the parts of the DC-DC converter, execute selection and design.And used the PWM to control MOSFET to stably control the output voltage to achieve savings cost and reduce the consumption of power. In order to test and verify the accuracy and feasibility of designed power banks, proposed eight different situation to experiment and research how to compromise output capacitors and output inductorsm to stable output voltage, reduce the size and reduce weight.
