For the conducted EMI problem in flyback switching power supply is more serious,the flyback switching power supply works and the reasons of conducted EMI are analyzed. By using the Saber software simulation model is proposed to build, and the simulation waveforms of the conducted EMI is obtained. Test of the conduction EMI waveform of the hardware circuit and comparison with experimental results the method is verified.
