Electromagnetic interference or compatibility is a challenge faced by circuit designers across all areas of research, applications and industries, and is the subject of strict regulatory requirements.
Darney's Circuit Modelling for Electromagnetic Compatibility, 2nd Edition shows how the analytical tools of circuit theory can be used to simulate the coupling of interference into, and out of, any signal link in the system being reviewed. This approach offers EMC testers and product designers a tool to work with at an early stage, before running expensive Faraday cage tests, which offers insight into whether a design is on the right track to achieving its design specification and so saving time and money.
The comparatively simple techniques explored in this book enable the design of equipment to be tailored to meet EMC requirements. A review of the construction of the wiring assemblies and the functions of the signals they carry allows critical links to be identified, then circuit modelling can be used to simulate the electromagnetic coupling mechanism of each critical link, allowing its performance to be analysed and compared with the formal requirements. Bench testing during product development allows any interference/compatibility problem to be identified and corrected, long before the manufactured unit is subjected to formal testing. The use of Mathcad and MATLAB(R) to perform analysis and assessment is also explored.
The first edition of the book was written by innovator in the field Ian B. Darney. This 2nd edition has been revised, expanded and updated by the author's former colleague and highly-experienced design engineer Chris M. Hewitt.
The book aims to equip electrical engineers working across all fields and sectors to investigate EMC problems using modelling techniques and general-purpose test equipment, enabling a more efficient and cost-effective circuit design process.
