Abstract:
A power system comprising a plurality of power supply units (â€œPSUsâ€ ), each PSU having an output that is coupled to the output of other PSUs in the power system, each PSU comprising:a power factor correction (â€œPFCâ€ ) assembly for receiving an AC input and generating a first DC output; a DC/DC converter assembly that is coupled to the PFC assembly, the DC/DC converter assembly receiving the first DC output and generating a second regulated DC output; and a control assembly that is coupled to the DC/DC converter assembly, the control assembly being operative to monitor the DC/DC converter assembly output and in response thereto to provide control signals to the DC/DC converter assembly, the control assembly comprising, a plurality of control assembly input circuits, the control assembly input circuits being operative to measure characteristics relating to the DC/DC converter assembly and operative to generate a measured characteristics output; a signal processor having a signal path to the control assembly input circuits, the signal processor being operative to receive the measured characteristics output, perform computations wherein the measured characteristics output is used in the computations, and generate a signal processor output; and a plurality of control assembly output circuits, the control assembly output circuits being operative to generate error signals based on the signal processor output.
