A Combined CM & DM Conducted EMI Modeling approach Application to a non-isolated on-board single-phase charger for electric vehicles

This paper presents a specific conducted electromagnetic interference (EMI) model for power electronics converters combining both common mode and differential mode emissions. This model allows the estimation of the conducted emissions solely based on the semi-conductors' switching functions. It offers the possibility to chain models in order to emulate the conducted EMI behavior of a global power electronics conversion system. The approach is applied to a non-isolated on-board single-phase charger for electric vehicles. Simulations using Psim software are carried. Future works consist in the experimental validation of the proposed method along with the determination of the frequency range of validity.
