分布式供電無法實現
一種可行的解決方案是，盡量縮短低壓直流傳輸導線的長度，將交流/直流電源設置在負載附近。 但這需要改變整個係統的供電方式，由“集中供電”改為“分布供電”，需要安排更多的交流“取電 點”，或者採用長距離的 230Vac 或 400Vac 交流傳輸線。在很多應用中，考慮到低壓要求或係統 設計要求等，無法實行這種方案。
普通的直流/直流轉換器方案
另一個可行的解決方案是在長距離低壓直流導線末端串入一臺直流/直流轉換器，作為“電壓補償 器”，以補償導線上的壓降引起的電壓波動。並不是所有的直流/直流轉換器都適用於此類應用，非常 重要的是，
1) 直流/直流轉換器要有較寬的輸入電壓範圍，允許的輸入低電壓要很低。
2) 直流/直流轉換器自身不能有過的輸入(起動) 電流需求。
PULS 普爾世的電壓補償器 CD5.241-L1
PULS 普爾世在開發電壓補償器“CD5.241-L1 ”時，認真考慮了這些應用需求，設計了 14-35Vdc的寬輸入電壓範圍，和主動式浪涌電流以及“軟”起動功能以避免普通直流/直流轉換器起動時的 輸入峰值電流。可以下述應用為例來說明它的特性。
