This paper presents the modeling method of conducted noise on AC/DC converter using SiC devices. The common-mode equivalent circuit is derived by obtaining the impedance characteristic of the parasitic component related to the conducted noise. In addition, two or more common-mode modeling circuits are necessary to simulate two or more resonance points. The validity of the equivalent circuits and modeling method is evaluated by comparing the experiment and simulation results.
