摘要
In the power electronic device and the electronic equipment installed in electric vehicles (EV), the flyback converter is most commonly used as the auxiliary power supply. The electromagnetic interference (EMI) emitted by a flyback converter can transmit directly through the power supply port to other power electronic devices powered by the same power supply system. In this paper, the mechanism of the conducted EMI emission of a flyback converter is analyzed. The equivalent circuits of differential- and common-mode interference are established in the frequency domain to realize the accurate prediction of the conducted disturbance of the flyback converter.
