The common mode and differential mode integrated EMI filter based on E1 core planar are illustrated and analyzed the integration principles. It builds simulation analysis verification on finite element electromagnetic fields and equivalent circuit of the common mode and differential mode integrated filter was gained and its design results were given. Circuit simulation and experiment result proved that it has a better filtering effect of using the common mode and differential mode EI core integrated filter.
