Demonstration Project Overview: DC Powering Architecture for Data Centers

This demonstration project focused on DC conversion at the equipment rack level. This approach converts the facility's supplied AC into high-voltage DC via a rack-mounted rectifier unit — the DC voltage under consideration is at 380 VDC, although 48 VDC is also a possibility. This approach concentrates the DC conversion into one unit/location in the rack, removing the AC to DC conversion function from the servers themselves.
