Using a flyback converter as a case study, an electromagnetic interference (EMI) simulation model including the non‐linear behaviour of an isolation transformer is developed. To take into account the non‐linearity of the transformer in the circuit simulation, the Jiles‐Atherton (J‐A) model that handles the non‐linear behaviour of the magnetic core is proposed. As the non‐linearity of the transformer affects mainly the differential‐mode (DM) conducted EMI but not the common‐mode conducted EMI, the simulation and experimental results presented in the study will focus on DM conducted EMI. The ability to include the non‐linear behaviour of a magnetic component in a power converter yields more realistic prediction that reflects the actual operating condition of the power converter, which prevents underestimation of DM conducted EMI.
