Abstract
Abstract A power distribution system in which a plurality of power supplies generate power of one or more regulated voltages, each voltage being received by regulator circuit that compares the regulated voltage against a predetermined reference voltage level and generates a digital control signal therefrom. Each power supply increases the regulated voltage when the respective control signal indicates that the regulated voltage is less than an optimum level.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
A control system for a power distribution system, comprising: a plurality of power supplies having controllable voltage outputs, jointly supplying power at a plurality of regulated voltages, and a plurality of regulator circuits, one associated with each regulated voltage, each regulator circuit receiving as inputs the associated jointly supplied regulated voltage and a reference voltage, and providing an output representative of a deviation of the associated jointly supplied regulated voltage from the reference voltage, the output coupled as a control input to each of the plurality of power supplies, the regulated voltage of a first regulator circuit being input as the reference voltage of a second regulator circuit.
Claim 2
Dependent Claim
108 words
A control system for a power distribution system, comprising: a plurality of power supplies having controllable voltage outputs, jointly supplying power at a plurality of regulated voltages, and a plurality of regulator circuits, one associated with each regulated voltage, each regulator circuit receiving as inputs the associated jointly supplied regulated voltage and a reference voltage, and providing an output representative of a deviation of the associated jointly supplied regulated voltage from the reference voltage, the output coupled as a control input to each of the plurality of power supplies, the regulated voltage of a first regulator circuit being input as the reference voltage of a second regulator circuit.
Claim 3
Dependent Claim
21 words
The control system of claim 1, further comprising a reference voltage device coupled to first regulator circuit as the reference voltage.
Claim 4
Dependent Claim
94 words
