摘要：

Modeling the common-mode behavior of power electronic systems can be a challenge. This research aims to simplify the process by developing a modeling approach based on Thevenin common-mode equivalent circuits. The Thevenin common-mode equivalent circuits prove to be both straightforward to construct and reliable in predicting worst-case common-mode behavior. In this paper, a theoretical understanding of the Thevenin-based modeling approach is first provided. Subsequently, methods to characterize the Thevenin parameters are established. The modeling approach is then validated experimentally on a dc micro-grid.
