直流轉直流轉換器

直流轉直流轉換器是用於將直流電從某一電壓以高效率轉換至另一電壓的電子裝置。直流轉直流轉換器廣泛用於系統與儀器中以轉換及分配直流電。直流電通常以系統電源供應器或電池的型態來提供。對於直流轉直流轉換器的輸入是非穩壓式直流電壓 Vg。轉換器產生電子元件 IC 需要的穩壓式輸出電壓 (5V 或 3.3V),具有的強度 (也可能是極性) 和 Vg 不同。


理想的直流轉直流轉換器應具備 100% 效率,但事實務上通常是 70% 至 95%。這一點透過開關模式,或元件消耗電力非常小的斬波器電路來達成。脈衝寬度調制 (PWM) 能控制與穩定總輸出電壓。


直流轉直流電源轉換器適用於眾多應用,涵蓋個人電腦的電源供應器、辦公室設備、太空船的電源系統、筆記型電腦、通訊設備與直流馬達驅動。
