Electromagnetic Compatibility and Interference In Modern Automotive Systems: A Comprehensive Analysis Of Integrated Circuit Susceptibility, Functional Safety, And Mitigation Strategies In Electric Vehicle Power Electronics

Abstract

The rapid evolution of the automotive industry toward electrification and autonomous driving has introduced unprecedented challenges regarding electromagnetic compatibility (EMC). As vehicles transition from mechanical systems to sophisticated electronic ecosystems, the density of high-power converters and sensitive integrated circuits (ICs) within a confined spatial environment has increased significantly. This research provides a deep investigative analysis into the mechanisms of electromagnetic interference (EMI) and its impact on automotive functional safety. By synthesizing international standards such as IEC 61967 and IEC 62132 with contemporary case studies of EMI-related vehicle recalls-including sudden acceleration incidents and airbag failures-this paper explores the critical intersection of power electronics and signal integrity. The study focuses specifically on the EMI characteristics of DC/DC converters, inverters, and smart high-side switches within Electric Vehicles (EVs). Furthermore, it evaluates the efficacy of advanced shielding techniques in high-speed communication protocols like 10G Automotive Ethernet and ADAS camera systems. The findings underscore a vital need for integrated EMI prediction modeling at the semiconductor level to prevent catastrophic failures in safety-critical systems.
