Technology giant Apple is reportedly testing the use of additive manufacturing (AM) technology (also...

A few basic system components are frequently used to mitigate or suppress electromagnetic interference (EMI) in devices. As engineers and technicians involved in compliance engineering, it is important to know what these components are, what they do, how they’re most effective, and when they’re ineffective.

Magnetic materials used in inductors and filters have specific functions and purposes. However, knowing which to choose can be confusing.

This paper provides an overview on the importance of ethical obligations to help ensure end-product safety and its certifications effectively address and satisfy component level application considerations. These are known as “Conditions of Acceptability” for most North American certification reports and “Application Considerations” for most European Union certification authority reports.

Most EMI issues are caused by a resonance that is excited somewhere in the system. It may be a resonance of a cable acting as an antenna or a heatsink energized by the power electronics switches bolted to it, becoming a good radiator. In this article, we look at the indicators that signal the presence of structural resonances and provide techniques for fixing the EMI issues. Practical case studies are presented to demonstrate the techniques.

The selection of component values for common mode filters need not be a difficult and confusing process. The use of standard filter alignments can be utilized to achieve a relatively simple and straightforward design process, though such alignments may readily be modified to utilize pre-defined component values.

While the selection of components in electrical equipment plays a crucial role, a sound understanding of the characteristics of safety-critical and high-integrity components can provide valuable information about the ways to advance and achieve safety goals.
