Abstract

A computer server rack for mechanically supporting and electrically powering computer servers is provided. The rack includes DC-to-DC conversion circuits which are configured to convert a relatively high DC facility voltage (e.g. 380 volts DC provided throughout a data center on busways and/or appropriate wiring) to DC voltage useable directly by a computer server (e.g. 12 volts DC). The conversion circuits are highly efficient and convert substantially all of power input to the circuits at the input voltage and input DC current to a high DC output current at a lower output voltage. The conversion circuits are distributed among the computer servers in an electrically parallel arrangement to provide a predetermined level of redundancy, to permit replacement of the circuits without disrupting power to the servers in the rack, to reduce variations in the voltage supplied to the servers along rack bus bars or power conductors as a result of the current flowing and the impedance of the bus bars or conductors distances between conversion circuits and servers distributed within the rack, and to increase the internal server volume dedicated to the servers.
