5、g, Simulation, and Reduction of Conducted Electromagnetic Interference Due to a PWM Buck Type Switching Power Supply   A. Farhadi  Abstract: Undesired generation of radiated or conducted energy in electrical systems is called Electromagnetic Interference (EMI). High speed switching frequen

6、cy in power electronics converters especially in switching power supplies improves efficiency but leads to EMI. Different kind of conducted interference, EMI regulations and conducted EMI measurement are introduced in this paper. Compliancy with national or international regulation is called Electro

7、magnetic Compatibility (EMC). Power electronic systems producers must regard EMC. Modeling and simulation is the first step of EMC evaluation. EMI simulation results due to a PWM Buck type switching power supply are presented in this paper. To improve EMC, some techniques are introduced and their ef

8、fectiveness proved by simulation.  Index Terms: Conducted, EMC, EMI, LISN, Switching Supply  I. INTRODUCTION   FAST semiconductors make it possible to have high speed and high frequency switching in power electronics 1 . High speed switching causes weight and volume reduction of equipment, but some unwanted effects such as radio frequency interference appeared 2 . Compliance with electromagnetic compatibility (EMC) regulations is
