Solutions to EMC Problems

This course covers the comprehensive understanding of Electromagnetic Compatibility (EMC) principles. It starts with the layout and control of interfaces, grounding and earthing principles, and electromagnetic shielding. The course delves into the theory behind shielding effectiveness, focusing on metallic plates and the phenomena of multiple reflection in the shield. It further explores the principles of shielded cables, transfer impedance of cylindrical shields, and surge protection components. For instance, the course explains how to reduce electromagnetic interference by dividing ventilation holes into several small holes or a mesh. The course also covers the principles of grounding or earthing in EMC, the role of grounding in shielding cables, and reducing radiated susceptibility. It concludes with a detailed explanation of system topology, control of interfaces, and the concept of waveguides beyond cut-off. This course has been developed by Prof. Daniel Mansson and Prof. Rajeev Thottappillil from KTH Royal Institute of Technology, Sweden for NPTEL.
