Abstract
Exemplary embodiments include An active impedance current-sharing circuit including: a power supply in electrical communication with a current sense resistor; a differential amplifier in electrical communication with the current sense resistor; a gate adjust amplifier in electrical communication with the differential amplifier; an ORing MOSFET in electrical communication with the gate adjust amplifier and the current sense resistor; a current share resistor in electrical communication with a current share bus and the gate adjust amplifier; and a current share output in electrical communication with the ORing MOSFET, wherein the circuit allows two or more power supplies that are not designed for current share to be connected in parallel and current share by actively modulating the ORing MOSFET between its linear and fully enhanced regions.
