Abstract

With the continuous improvement of vehicle safety and reliability requirements, EMI has been paidmore and more attention. This paper introduces the basis of electromagnetic compatibility, compares and analyzeshe generation mechanism and prevention methods of common mode interference and differential mode intererence inelectromagnetic interference, and combined with practical cases, on the premise of mceting the vehicle insulationrequitements, the electric drive system is modified to meet the certification requirements.

Key words

EMI / common mode interference / differential mode interference / Y-capacitance
