EMI filter is becoming an essential part for modern power converter products, contributing to significant cost and sizes. Effective EMI filter design involves the identification and separation of common-mode (CM) and differential-mode (DM) conducted noises of the converter. In this paper, the impact by the diode conduction patterns on the EMI characteristics of a three-phase diode front-end converter is analyzed. There are classical two-line CM and DM noises similar to single phase cases corresponding to the two diode conducting case, the "mixed-mode" CM noise corresponding to no diodes conducting cases, and the three-line CM and DM noise corresponding to commutation cases. Though the present filter design based on single-phase approach seems to be adequate as a worst-case design, a more generic approach considering all three conditions together may provide opportunities for filter design optimization.
