| Abstract: | As an essential component of hybrid electric vehicle（HEV）,the DC/DC converter is one of the main electromagnetic interfering sources.The electromagnetic interference（EMI）generating mechanisms of the DC/DC converter is elaborated,as well as the approaches that electromagnetic interference spreads from.The measures for EMI suppression are afforded and their validity is verified by testing.The results show that these measures are effective. |
