Abstract

Electromagnetic interference/compatibility in electrical and electronic systems

Mohammed Saleh Al Salameh

This review paper addresses the importance of considering electromagnetic interference/compatibility (EMI/EMC) in every design stage of manufacturing a product that involves electronic and/or electrical subsystems, and thus EMC should be a major design objective. Also, EMC should be a part of the curriculum of electrical engineering at educational institutions. Both narrowband and wideband sources of noise and interference are identified, and terminology of EMC is introduced. The noise path from the source to the receptor is identified. Real-world examples of electromagnetic interference in different systems, such as cars, trucks, aircrafts, warships, display screens, and computer systems, are illustrated. Radiated and conducted emissions as well as radiated and conducted susceptibility are described. The ability of cables including the power cord to conduct interference is emphasized. Static discharge and electromagnetic pulse (EMP) which can cause interference and malfunction to electronic systems are analyzed. TEMPEST techniques for secure communications and data processing are outlined. Regulations in industrial countries enforcing compliance with EMC requirements are addressed. General strategies to counteract interference are introduced
