Patent ID: 7323794

Claim:
An information handling system having independent control of output current balance between paralleled power units, said system comprising: an information handling system having a plurality of power supply units, the plurality of power supply units adapted for receiving power from a power source and providing voltages necessary to power the information handling system, the plurality of power supply unit outputs being connected in parallel, wherein output current from each of the plurality of power supply units is independently controllable; a current measuring circuit for each of the plurality of power supply units, the current measuring circuit measures actual current drawn from a respective one of the plurality of power supply units; a current adding circuit for each of the plurality of power supply units, wherein the current adding circuit adds a pseudo current to the measured actual current for generating an apparent current of the respective one of the plurality of power supply units; and a load balancing circuit for balancing the apparent current of each of the plurality of power supply units to a shared current value, wherein the pseudo current is used to reduce the actual current supplied by the respective one of the plurality of power supply units.
