Abstract :
AC/DC-DC/DC has been widely used in switched-mode power supply (SMPS). In this paper, the MM EMI coupling and suppression mechanisms of this type of the flyback converter will be given and its effects on DM capacitor will also be elaborated. Planar DM capacitor design examples including the theoretical and analysis of the flyback MM EMI will be used. Simulation results based on Saber will be carried out to show the validity of this design.
