Abstract
Today´s technology in data center power is moving toward the perspective of the load´s need for VDC (Volts Direct Current) Power and away from a focus on how to convert VAC (Alternating Current) Grid Power to something usable. BUT, converting to Data Center VDC Power Systems is not enough. This is not VAC verses VDC, not analog verses digital, not Westinghouse verses Edison. Simply put, it is the enhanced reliability, lower cost and maintenance expense, dramatic real estate reduction, and effective green power integration when focusing on the load´s need for VDC Power. PLUS, increased efficiency is important and VDC does provide, in all cases an improvement. 380 VDC Power is the global format of choice. While we want to say “Edison was right”, we need to instead recognize that this world has evolved to where the demarcation line between VAC and VDC has made a shift. The VDC load is no longer just the chip, it is now 80% of the building enabled by power electronics and justified by the holistic business value of VDC.
