| Abstract |
Reliability performance of a DC UPS system having redundant (n+I) rectifiers and battery back-up of several hours can
be theoretically very high. The existence of common mode failures can, however, significantly reduce or even totally destroy the
naturally high reliability performance. Remote controlling of output voltage, output overvoltage monitoring and shut down as well as improper configuring of output voltage levels are the most common causes of common mode failures. This paper describes the
methodology to analyze the availability and reliability performance based on Markov chains. Methods and ways are introduced and
drscussed by means of which the existence of common mode failures can be minimized. The methodology is based on the Ideas derived from fuzzy logic and labelled fuzzy thinking. |
