    This digest presents a comparative study of EMI performance in TCM and ITCM PFC converters, including both common-mode (CM) and differential-mode (DM) noise. A frequency-domain EMI prediction method is developed to directly estimate noise spectra without relying on time-intensive transient simulations. The predicted results are validated against experimental measurements, showing close agreement in peak noise magnitudes and overall spectral trends. This prediction approach provides designers with a systematic and efficient framework for EMI-aware PFC design.
