An End-User's Guide to Selecting AC/DC Power Plant Architecture. Bulk vs. Distributive

Abstract

With recent advancements in densely packed switchmode -48 VDC rectifier designs, a new era of battery technologies such as lithium ion (LI) and lithium metal polymer (LMP), the rising cost of copper, high cost of capital and the latest National Electrical Code (NEC2005), it's time again to revisit the distributive vs. bulk question. The intent of this paper is to assist an end-user in determining which DC power plant architecture to select when designing a telecommunication equipment room layout. This paper will take into account the majority of considerations to be addressed when selecting an AC/DC power plant Architecture. The models will be presented by one (1) bulk solution and three (3) distributive solutions
