Analysis and control design of paralleled DC/DC converters withcurrent sharing

摘要

This paper presents a general small-signal stability analysis ofnparalleled power converter systems. The framework specializes to includenboth the “democratic” and “master-slave”ncurrent-sharing schemes. Design examples illustrate how to obtain stablencurrent sharing. The authors show how paralleled power converters cannbecome unstable (even when active current sharing is absent) and discussnthe influence of the number of converters paralleled
