摘要
从国内外研究直流供电代替交流UPS供电的不同出发点入手,分析了以提高节能效率和供电可靠性为目的的不同供电电压等级选择和系统设计思路,阐述了这两种直流供电系统的基本原理。通过对国内外直流供电技术供电可靠性、节能效率及安全性、投入产出的对比分析,论证了创新性地使用240 V直流供电技术的科学性和大规模推广的可行性。
The analysis was made for the nominal voltage selection and system design method which was based on energy efficiency prompt and power reliability increasing, these different goals to replace AC power system by DC power system, and these two direct current power supply system was introduced. It was compared that the reliability, the efficiency, the security and the input/output ratio which could prove the scientifically and large-scale application feasibility of 240 V direct current power supply system.
