分布式供电无法实现
一种可行的解决方案是，尽量缩短低压直流传输导线的长度，将交流/直流电源设置在负载附近。 但这需要改变整个系统的供电方式，由“集中供电”改为“分布供电”，需要安排更多的交流“取电 点”，或者采用长距离的 230Vac 或 400Vac 交流传输线。在很多应用中，考虑到低压要求或系统 设计要求等，无法实行这种方案。


普通的直流/直流转换器方案
另一个可行的解决方案是在长距离低压直流导线末端串入一台直流/直流转换器，作为“电压补偿 器”，以补偿导线上的压降引起的电压波动。并不是所有的直流/直流转换器都适用于此类应用，非常 重要的是，
1) 直流/直流转换器要有较宽的输入电压范围，允许的输入低电压要很低。
2) 直流/直流转换器自身不能有过的输入(起动) 电流需求。


PULS 普尔世的电压补偿器 CD5.241-L1
PULS 普尔世在开发电压补偿器“CD5.241-L1 ”时，认真考虑了这些应用需求，设计了 14-35Vdc的宽输入电压范围，和主动式浪涌电流以及“软”起动功能以避免普通直流/直流转换器起动时的 输入峰值电流。可以下述应用为例来说明它的特性。
