Title: Modeling, simulation, and reduction of conducted electromagnetic interference due to a PWM buck type switching power supply
Abstract: Undesired generation of radiated or conducted energy in electrical systems is called electromagnetic interference (EMI). High speed switching frequency 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 electromagnetic 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 effectiveness proved by simulation.
