Tutorial Title: Modeling and Reduction of Common-Mode Noise in Power Converters

This talk provides the modeling and reduction of common-mode (CM) noise in power converters. In the first part, the CM noise modeling approaches are presented. The transformer inter-winding capacitance, a critical propagation path for the CM noise in isolated power converters, will be investigated. After that, a generalized lumped capacitance model will be discussed, which describes the behavior of CM noise propagation for high frequency transformer. Based on the lumped capacitance model, the equivalent noise source (ENS) concept will be introduced for deriving the CM noise model of basic isolated power converters, and the effect of circuit configuration on the CM noise will be further discussed. In the second part, the CM noise reduction techniques will be expolred. The shielding-cancellation (SC) technique and the hybrid passive cancellation (HPC) method are firstly investigated, which improves the CM noise reduction of conventional shielding technique. For the converter with a complicated CM noise propagation path, such as the phase-shift full-bridge (PSFB) converter, the CM noise reduction by combining symmetry circuit and passive cancellation will be presented. Finally, the CM voltage cancellation (CMVC) method will be provided for a better understanding of the CM noise reduction techniques in power converters.
