With the rapid development of switching frequency and power density of power factor correction(PFC) converter, the conducted electromagnetic interference(EMI) of PFC converter is becoming increasingly severe. Different from traditional EMI modeling using FFT for frequency domain analysis, this paper established an EMI analysis model based on mathematical modeling of EMI receiver. Through simulation, this paper verified the reliability of analysis model and localized parasitic parameters that have significant impact on conducted EMI. Simulation results also verified that there is a significant difference between EMI receiver model and FFT, and the result of analysis model using EMI receiver model is closer to EMI simulation spectrum. Through experiment, this paper verified the reliability of EMI receiver model.
