Patent ID: 7732941

Claim:
A multimodule current sharing system, comprising: a plurality of power modules sharing current on a common bus; wherein each of the plurality of power modules includes circuitry for controlling an amount of current correction applied to each of the plurality of power modules, wherein the circuitry for controlling further includes; first circuitry for generating an error voltage responsive to a reference voltage and an output voltage; a correction current source applied to the first circuitry wherein a current provided by the correction current source includes a combination of a current of one of the plurality of power modules and a selected offset current subtracted from an average current of each of the plurality of power modules; and a first resistor connected to the first circuitry, wherein a value of the first resistor controls the amount of voltage correction applied to the first circuitry by the correction circuit source, wherein the value of the first resistor may further enable or disable current sharing among the plurality of power modules.
