Abstract
A simple, application-oriented, transfer function model of paralleled converters employing master-slave current-sharing (MSC) control is developed. Dynamically, the master converter retains its original design characteristics; all the slave converters are forced to depart significantly from their original design characteristics into current-controlled current sources. Five distinct loop gains to assess system stability and performance are identified and their physical significance is described. A design methodology for the current share compensator is presented. The effect of this current sharing scheme on "system output impedance" is analyzed.Keywords
