Michel Mardiguian . has for many years been an internationally recognized writer and lecturer. Michel’s popular series of EMC-articles in Electronic Environment has also been published on the magazine’s international website with readers from all over the world. Michel Mardiguian has now compiled the large number of articles and course material, for a comprehensive handbook.

Some simple hints . for identifying and fixing EMI troubles. This second part of our EMI Troubleshooting guidelines is devoted to investigation and cure of EMI susceptibility problems. Since, according to our former article (Ref.1) conducted tests are faster and easier to perform, we will concentrate on these and avoid more complex and expensive radiated susceptibility test set-ups. The first half of this article will address the situation where the equipment at stake is still in the plant or lab, at the end of its development phase or in an early stage of production. The second half will cover the more difficult cases where the faultly equipment is already in service, installed at some customer site.

Some simple hints . for identifying and fixing EMI troubles. This article covers the essential aspects of a domain which is seldom addressed in current EMC litterature: «What to do when an equipment – or a whole system – is failing the tests or experiencing Interference (EMI) problems ?». Whatever we are dealing with a prototype at the end of its development phase, failing one or several EMC tests, or an already installed equipment that exhibit on-site problems, we face a situation that must be solved quickly, with an equipment that cannot be deeply modified.

Our former . eight EMC articles were aimed at familiarizing unaware readers with the fundamentals of EMI/EMC, justifying the EMC norms and testing, and explaining in simple terms the five basics interference coupling mechanisms, with the essential guidelines for controlling them. The present article goes deeper into one of the simplest, most compact and economical piece of the entire EMC arsenal: the filter. With current handling ranging from tens of Amp for signal filters up to more than hundred Amps for power line filters, they exist in all sorts of size, volume and packaging. They can be optimized against Common Mode (CM) or Differential Mode (DM) interference, or both.

Preamble . Our former EMC articles reviewed four of the 5 principal conduction and radiation coupling mechanisms, as they affect equipment/ system susceptibility and emissions. The last ones (EMC Articles #6 and 7) were addressing the shielding of equipment boxes, from the smaller hand-held devices up to large cabinets or even entire rooms. The present article is covering the 5th, very important coupling mechanism: How the various disturbances that exist on the power mains (public AC distribution, ship or aircraft AC distribution, vehicle dc distribution… etc) can find their way from their source down to the electronic components of a system?

Our former . EMC articles reviewed the principal conduction and radiation coupling mechanisms, as they affect equipment/system susceptibility, and the last one (EMC Article #5, June Issue) was addressing Shielded Cables. The present article is focusing on the shielding of equipment boxes, from the smaller hand-held devices up to large cabinets or even entire rooms.

This article . is a summary of the Keynote Speech given by Michel Mardiguian and Ulf Nilsson at Electronic Environment Conference in 2016. The intention was to give an overview of what EMC is, how it influences an organisation and to motivate management to implement an EMC culture in their organisation.
