On Spread Spectrum for DC Grids: Low-Frequency Conducted EMI Mitigation and Signal Integrity Disruption in Serial Communication Links (2023)
Journal Article

This article addresses the effects on nearby communication systems when spread spectrum modulation techniques are used for a dc-dc power converter. These interactions can be found in modern smart grids and automotive power networks in which the combi...

The Effect of Spread Spectrum Modulation for a Buck Converter Coupled with a Single Wired Communication Link (2021)
Conference Proceeding

This paper explores the effect of using a Spread Spectrum modulation technique with a Buck Converter on a communication cable coupled at the input voltage. The EMI created by the switching of the power converter generates damped oscillations on the d...
