    Abstract: 在筆記型電腦之設計實現上,本論文提出兩個可以節省電池的消耗與提高使用時間之調整方式。首先,本論文設計實現一個系統控制?路,其可以利用環境光源的強弱進行自動調光動作,使變頻器可以隨著環境光源的強弱進行自動調光動作,此方式將可以不需使用人工切換筆記型電腦上之明暗控制鍵,自動達到節能目的並且延長筆記型電腦電池的使用時間。此外,在變頻器與冷陰極燈管搭配上,本論文提出一個變頻諧振方式,此方式透過實際調整變頻器上全橋式變頻諧振電路之串聯電容(Cs)與並聯電容(Cp)的電容值來提升變頻器的效率。
    In the design and implementation of notebook PCs, two modification methods are proposed to reduce the wastage of its battery and extend its used time. First, a control circuit is proposed to automatically adjust the brightness of the screen of notebook PC based on the measured light of environment. Then, in the module of the inverter and Cold Cathode Fluorescent Lamp (CCFL), a method to get the actual data of capacitors Cs and Cp is proposed so that it can improve the work efficiency of inverter.
