Abstract
A power system includes a plurality of power 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 and 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 converter assembly.
