Abstract
Distributed power architecture advantages span from improvements in technical performance to substantially shorter development time to market. Although these are valuable attributes, none is more important than lower cost. Seldom are other features so predominant that they would command a sizable price differential. So, although the paper discusses in some detail the value of improved performance and business merits of the distributed architecture, it primarily focuses on the economic value of distributed power. The paper demonstrates that not only can distributed power be cost competitive with other powering solutions, it may in fact hold a sizable cost advantage. Some of these advantages are derived from the pay-as-you-grow concept provided by the distributed power architecture. Others are derived from the ability to position the downstream power converter of the architecture in line with system failure groups, thereby eliminating the need for redundancy in order to maintain a high level of availability.
