分布式供電無法實現(xiàn)
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。 但這需要改變整個系統(tǒng)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”,或者采用長距離的 230Vac 或 400Vac 交流傳輸線。在很多應用中,考慮到低壓安全要求或系統(tǒng) 設計要求等,無法實行這種方案。
普通的直流/直流轉(zhuǎn)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(zhuǎn)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。并不是所有的直流/直流轉(zhuǎn)換器都適用于此類應用,非常 重要的是,
1) 直流/直流轉(zhuǎn)換器要有較寬的輸入電壓范圍,允許的輸入低電壓要很低。
2) 直流/直流轉(zhuǎn)換器自身不能有過高的輸入(起動) 電流需求。

PULS 普爾世在開發(fā)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的寬輸入電壓范圍,和主動式浪涌電流抑制以及“軟”起動功能以避免普通直流/直流轉(zhuǎn)換器起動時的 輸入峰值電流??梢韵率鰬脼槔齺碚f明它的特性。
