摘要
对传统交流UPS和直流UPS应用于计算机的供电结构进行分析,证明了传统交流UPS在功率级上是重复冗余的,从运行效率、经济性和可靠性角度论证了无逆变结构的直流UPS更适合计算机的供电保障,最后提出了几种无逆变器结构的UPS方案。
In this paper, we compare the structures of the conventional UPS and DC UPS for computers and prove that the conventional UPS is redundant in power level. However, the DC UPS without inverters has relatively higher efficiency, better reliability and lower cost, so it is more suitable for computers. And we propose several non-inverter UPS solutions at the end of this paper.
