With the advancement of high-frequency switching devices, electromagnetic Compatibility (EMC) and electromagnetic interference(EMI) have become important problems in power converters. Any power converter is a primary source of the EMI, because the voltages and c urrents c ha nge very rapidly due tothe high frequency switching of the power devices. The EMI signals can be transmitted to the other electronic systems through space radiation or conduction along cables.How to handle these issues is a critical technology in power converters.The main objective of this special session isto share new research results and potentialsin modelling,miti gatio ntechnologya ndEMI standard.
