產(chǎn)品詳情
一種可行的解決方案是,盡量縮短低壓直流傳輸導(dǎo)線的長度,將交流/直流電源設(shè)置在負(fù)載附近。 但這需要改變整個(gè)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(diǎn)”,或者采用長距離的 230Vac 或 400Vac 交流傳輸線。在很多應(yīng)用中,考慮到低壓安全要求或系統(tǒng) 設(shè)計(jì)要求等,無法實(shí)行這種方案。
普通的直流/直流轉(zhuǎn)換器方案
另一個(gè)可行的解決方案是在長距離低壓直流導(dǎo)線末端串入一臺(tái)直流/直流轉(zhuǎn)換器,作為“電壓補(bǔ)償 器”,以補(bǔ)償導(dǎo)線上的壓降引起的電壓波動(dòng)。并不是所有的直流/直流轉(zhuǎn)換器都適用于此類應(yīng)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(dòng)) 電流需求。
PULS 普爾世的電壓補(bǔ)償器 CD5.241-L1
PULS 普爾世在開發(fā)電壓補(bǔ)償器“CD5.241-L1 ”時(shí),認(rèn)真考慮了這些應(yīng)用需求,設(shè)計(jì)了 14-35Vdc的寬輸入電壓范圍,和主動(dòng)式浪涌電流抑制以及“軟”起動(dòng)功能以避免普通直流/直流轉(zhuǎn)換器起動(dòng)時(shí)的 輸入峰值電流??梢韵率鰬?yīng)用為例來說明它的特性。
