Abstract

A power system includes a plurality ofpower supply units ("PSUs"), each PSU having an output that is coupled to the output of other PSUs in the power system. Each PSU includes a power factor correction ("PFC") assembly for receiving an AC input and generating a first DC output. A DC/DC converter assembly is coupled to the PFC assembly, and receives the first DC output an d generates a second regulated DC output. A control assembly is coupled to the DC/DC converter assembly, and is operative to monitor the DC/DC converter assembly output and in response thereto provide control signals to the DC/DC 10 converter assembly.
