English Abstract

This article presents a method for characterization of common-mode chokes aimed at constructing accurate virtual prototypes of electromagnetic interference filters. This method is based on a general modal analysis that identifies the natural modes of a symmetric four-port network in a power line. Natural modes excited in the setups defined in the CISPR-17 norm to characterize filtering devices are...
