本論文旨在評估溫度對不同架構的筆記型電腦充電器效率的影響，針對混合型升壓(HPB)充電器與窄電壓直流(NVDC)充電器兩種不同充電器架構在一般室溫與高溫工作環境下的效率反應。經由實驗找出溫度對系統效率的相對關係，透過有效的散熱模組與風扇的設計，力求迅速降低系統所產生的熱量，減少溫度對系統的效能影響，並且改善風扇噪音。

The design of laptop is more and more challenging than before. In this thesis, the focus is to evaluate the charger efficiency of two different battery charger architectures, i.e. hybrid power boost (HPB) charger and narrow voltage direct current (NVDC) charger, between the room temperature and higher ambient temperature in computing system. First, the system impact aroused from temperature is explored by experiments. Then by using proper thermal dissipation solution and fan-cooling design to reduce the heat generation and increase the system efficiency, as well as fan noise suppression.
