Abstract :
A practical, `user-friendly´ methodology is developed to study the behavior of current-shared converters. It applies average modeling, analysis and simulation to examine the static conditions and small-signal stability of converters that operate in average current sharing (ACS) mode. Simple expressions for stability criterion were developed and applied to assess the influence of the number of paralleled modules on the stability and dynamics of the converters system
