DC v AC: Which is more efficient? (Hint: neither)

A quantitative comparison of the two types of power distribution for data centers

Published 8th January, 2013 by Neil Rasmussen and James Spitaels, Schneider Electric

In a detailed quatitiative efficiency comparison, Schneider shows that a move to a DC-based architecture on the basis of efficiency is unwaranted. The latest AC and DC power distribution architectures are shown to have virtually the same efficiency.
