“…The suggested technique characterizes the production emissions of the power converter within the frequency range of 9-500 kHz considering the double Fourier analysis and closed-loop impedance. Extra details about the modeling of DM noise, closed-loop input impedance, and the frequency behavior have been reported in [11] for single-phase non-interleaved boost PFC. The DM noise spectrum of each switch is presented by (6), where it contains a DC offset value, baseband harmonics, carrier group harmonics, as well as sideband harmonics:…”

“…EMI filter is effectively employed for reducing the EMI noise emissions. The dependency of the required EMI filter attenuation to the first peak of the EMI level has led to many modeling approaches to estimate the EMI peak level measurement in the Band A and B frequency ranges [7] - [11]. Additionally, it is highly acceptable that the reduced input ripple current results in the reduction of the DM EMI noise magnitude and filter attenuation requirements, which make the DM EMI filter size smaller and the corner frequency higher [1].…”

“…It is only suitable for EMI filter designing for standard phase shift interleaved and frequency above 150 kHz. Analytical DM EMI estimation is proposed for non-interleaved PFC in [11] for Band-A. However, there are no fundamental studies despite reported EMI noise issues to estimate the EMI level for interleaved boost PFC based on the phase shift's dependency, which can be investigated to minimize the DM EMI noise.…”

Interleaved power factor correction (PFC) is widely used circuit topology due to good efficiency and power density for single-switch boost PFC. As the differential mode (DM) electromagnetic interference (EMI) noise magnitude depends upon the input current ripple, this research details a comprehensive study of DM EMI filter design for interleaved boost PFC with the aim of minimizing the component size. It is also demonstrated that the different numbers of interleaved stages and switching frequency influence the filter attenuation requirement and, thus, the EMI filter size. First, an analytical model is derived on the basis of the Norton equivalent circuit model for the differential mode noises of interleaved boost PFC within the frequency range of 9-500 kHz. The derived model can help identify the optimal phase shifting among the interleaved boost converters in order to minimize the considered differential mode noises at the filter design frequency. So, a novel phase-shift method is developed to get a minimized attenuation required by a filter in Band B. Further, a volume optimization of the required DM filter was introduced based on the calculated filter attenuation and volumetric component parameters. Based on the obtained results, unconventional and conventional phase shifts have demonstrated a good performance in decreasing the EMI filter volume in Band B and Band A, respectively. A 2-kW interleaved PFC case study is presented to verify the theoretical analyses and the impact of phase-shifting on EMI filter size.

Wide-bandgap power devices have enabled singlephase totem-pole (TP) power factor correction (PFC) converter designs to be switched at several tens of kilohertz under hardswitching and hundreds of kilohertz under soft-switching. It is straightforward to analyze and compare the volume of boost inductor for TP PFC converters having multileg and multilevel configurations operating under continuous-conduction-mode (CCM) and critical-conduction-mode (CrM) at various switching frequencies; however, the impact of topology and switching frequency selections remains unchallenged for generated differential mode (DM) noise. This article proposes a unified and generalized DM noise estimation method for multileg, and multilevel TP PFC converters operated under both CCM and CrM operation modes. The method has been verified with simulation results obtained from various TP PFC topologies, as well as experimental results obtained from singleleg CCM and 4-Level CCM TP PFC converters. The empirically determined boxed sizes of DM filters have been compared among various TP PFC topologies, and the best switching frequency for each topology has been determined with the integration of boost inductor volume comparison.
