Consideration of Improving Accuracy of Conducted Noise Modeling on AC/DC Converter Using SiC-Device

This paper presents the modeling method of conducted noise on AC/DC converter using SiC devices. The common-mode equivalent circuit is derived by leakage current. considers multiple resonance points. In addition, EMI filter for power supply modeled and inserted into simulation. usefulness validity this are shown comparing simulation results measurement after inserting filter. Then, in order to consider more improve precision simulation, a genetic algorithm used determine parameters circuit, shown.
