In this study, we investigated conducted electromagnetic disturbances generated by a single-phase diode bridge rectifier with a boost converter, which is frequently encountered in power electronics. We propose a technique that can be used to improve the electromagnetic interference (EMI) performance. Our study deals solely with conducted EMI and its two types, the commonmode and differential-mode noise, in power converters. Our study focuses on the suppression of conducted EMI emission from a conventional boost converter. The experimental results were compared with the simulation results.
