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

In many published articles, expected improvements of 10% to 30% in efficiency have been claimed for DC over AC. But, as you would not compare the performance of a new server technology to the performance of a server made ten years ago, it is similarly inappropriate to compare hypothetical DC power distribution efficiency to the efficiency of older legacy AC power distribution systems. The important comparison is not between past and future alternatives, but between current and future alternatives.
