A Quantitative Comparison of High Efficiency AC vs. DC Power Distribution for Data Centers

A Quantitative Comparison of High Efficiency AC vs. DC Power Distribution for Data Centers

Cover

Recent findings suggest that the latest high efficiency AC and DC power distribution architectures are shown to have virtually the same efficiency, suggesting that a move to a DC-based architecture is unwarranted on the basis of efficiency.

This paper explains why by comparing the most efficient DC and AC power distribution methods. Also included is an analysis of the effects of power distribution efficiency on the cooling power requirement and on total electrical consumption.
