EMC in Product Development (Part 8)

This article is a part of a series of texts that will deal with the EMC challenge in terms of project management and the practical EMC activities at different stages in the project flow. Different companies all have their own way of describing their project flow, so to keep it simple we will use the labels as given in Figure 1. We can call it a generic project flow. The picture only describes the basic outline of the work packages. These articles will describe the actual practical work we want to do in the project to “make EMC work” in a time- and cost-efficient way. Each part of our series will fill in the details for each part piece by piece. This is the final 8th part – The Fast Track – in the series of articles.

How will 6G affect EMC?

The development within . the next generation of mobile technologies is going on for 5G. At the same time, research has already started for the future 6G. This research is in its initial stages and no agreements about key technical parameters and standards have yet been done. However, some suggestions on general principals and goals have been published from different actors. It is therefore interesting to see how these visions will affect the area of Electromagnetic Compatibility (EMC) in a larger sense.

Practical Consequences of Electromagnetic Interference in Wireless Applications

The use of wireless applications . is continuously increasing in the society. Together with the overall increased use of electronics in general, the total electromagnetic environment is increasing around wireless systems. The effect of interference does not always appear as interruption in communication, but can appear as more or less gradually performance degradation for the user. In this article, some of these interference consequences are discussed and examplified.

Measuring wireless performance of vehicles

Wireless connectivity . in cars is becoming more and more important. The functionality of the cars depends on a reliable wireless communication, e.g., for safety systems, infotainment, traffic warnings and updates of software and maps. To ensure that the desired and required wireless communication is achieved, extensive testing needs to be performed. Today a lot of the testing is done with drive-tests out in the field. However, this is both expensive and can only be done late in the development process, which makes it hard to modify the product.

Report from EMC Europe 2019

EMC Europe . International Symposium on Electromagnetic Compatibility was arranged the 2 – 6 September in Barcelona Spain. It was locally organized by Universitat Politècnica de Catalunya, Campus Nord. EMC Europe is the major European conference on Electromagnetic Compatibility and covers a wide area of topics within EMC. As usual, the conference had tutorials, workshops, poster sessions and oral sessions. High quality scientific and engineering papers were presented in a variety of themes within EMC.

EMC Challenges and Solar Panel Systems

The use of . solar panel systems is rapidly increasing and some of these systems are co-located in the vicinity of wireless systems. Measurements have shown that the radiated emission from solar panel electronics can reach considerable levels, in some cases even above CISPR 22 Class B. Here, examples of interference impact is discussed for two examples of wireless applications, air traffic control communications (ATCC) and High-Frequency (HF) communications. The overall conclusion is that co-location of solar panel systems with wireless communications, must be carefully analyzed not to create interference problems.

ESD – Design / Harden Equipment for ESD Immunity (Part II)

Preamble: . As for any organized EMI control, ESD protection consist in anticipating or correcting the unwanted effects of an hostile electromagnetic ambient. Like many EMI threats, ESD manifests through conducted and radiated phenomena, with the latest being often the dominant mode. But there is a unique aspect to ESD, not found in common radiated EMI episodes where the victim box and cables are illuminated by a uniform field. Instead, ESD generates locally a strong field pulse, typically > 1kV/m near the discharge point, dropping quickly as one move away. Therefore, although ESD hardening should be part of a general EMI control, not handled as a separate constraint, some classical EMC solutions may not be sufficient and should be complemented by additional protections.
