模块化UPS的分散旁路和集中旁路方案对比分析

Comparison of Centralized and Decentralized Bypass Solution of Modular UPS

熟悉模块化UPS发展的业内同仁应该都了解，模块化UPS的系统架构从开始就有两条不同的技术路线：分散旁路和集中旁路。本文从技术的来源和性能可靠性方面对比这两种方案的优缺点，并深入剖析造成这两种技术方案差异的原因。

As we know, there are two different types of bypass structure for modular UPS solution：centralized bypass and decentralized bypass. This paper discusses origins of different solutions and analyzes their performance and reliability, which compares advantages and disadvantages of the two structures. This paper also gives a deep insight of the reasons for the difference between the two structures.
