ABSTRACT:
A plurality of power supplies are connected in parallel, each power supply isolated from the others using a non-linear isolation element such as a barrier diode. Feedback is furnished around the non-linear isolation element such that the voltage drop of the isolation element is reduced to be within the regulation range desired. The non-linear characteristic of the isolation element combined with feedback produces an output impedance which is low for high currents, and exponentially higher for low output currents for current sharing versus output offset voltage improvement.
