摘要：

This paper presents a general small-signal stability analysis of paralleled converter systems. The framework specializes to include both the "democratic" and "master-slave" current-sharing schemes, Design examples illustrate how to obtain stable current sharing, We show how paralleled converters can become unstable (even when active current sharing is absent) and discuss the influence of the number of converters paralleled.
