Insights into Electromagnetic Interference in Non-Isolated DC to DC Converters: A Contemporary Analysis

Abstract

This article provides an in-depth exploration of Electromagnetic Interference (EMI) in Non-Isolated DC-to-DC Converters (NIDDCs), an increasingly significant topic due to the growing need for power conversion systems that are both efficient and compact. As these converters find application in various fields, from consumer electronics to automotive and industrial sectors, it becomes essential to address and mitigate EMI to ensure reliable, interference-free operation. The study investigates the primary sources of EMI in NIDDCs, such as switching noise, parasitic elements, and layout-related interference, and analyses the complex pathways through which these disturbances spread. The article assesses strategies for mitigating EMI, including advanced filtering techniques and optimized circuit design. It explores new advancements in NIDDC design, including integrating digital control, using wide-bandgap semiconductors, and investigating innovative converter topologies to minimize EMI at its source. By synthesizing contemporary research and industry practices, this review aims to provide a thorough understanding of the current EMI challenges in NIDDCs and to suggest future research directions in this essential field of power electronics.
