Abstract：The differential-mode(DM) electromagnetic interference(EMI) noise of two-phase interleaved Boost PFC converter operating in CRM with non-coupled and coupled indcutor are analyzed. The DM noise spectra are calculated based on an EMI receiver model and the worst spectra are obtained. Furthermore, in accordance with the relation ship between the magnitude of inductor current ripple and the DM noise, the worst conditions which see the maximum noise at 150kHz are figured out. Finally, the mathematical and experimental results are provided to verify the analysis.
