Abstract

This paper presents a simplified conducted EMI toolkit based on the basic circuits and concepts of power electronics. The simplified results of the EMI toolkit is to introduce the effect of conducted EMI caused by self-resonant frequency (SRF) of the passive components, reverse recovery time of diodes, switching frequencies, gate drive control, snubber circuit, parasitic capacitor of heat sink, EMI filtering, total harmonic distortion (THD) and conducted EMI. Those basic phenomena can lead designing engineers and students to understand the EMC concept, focused on only conducted emission, using step-by-step of the experiment.
