Abstract :
A method for assessing the small-signal stability of paralleled converters with active current sharing is derived. The method is general and can be applied to systems with any number of converters. For identical converters, the method results in a particularly simple stability criterion. Illustrative examples show application of the analysis method. Design considerations for using the method are also provided
