Design

This is the second in a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques.

Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 design requirements, creating project confusion with significant design and cost implications. This article focuses on bringing some clarity to the differences between ICS/ICD-705 design guidance and NSA 94-106 performance requirements. The related secure facility design and construction process is also reviewed.

End-product manufacturers can help protect against supply chain disruptions that impact the availability of listed or recognized components by proactively identifying suppliers who can provide substitute components that conform with their listing requirements.

This is the first of a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques.

Our knowledge of ESD and how to control it has grown significantly over the past 50 years. This article maps the history of that journey.

In this article, we establish design guidelines of a spread spectrum modulation circuit as it relates to CISPR 25.

The most common characterization of ground rods actually differs from what is observed in the case of lightning. This article discusses what is observed and how that affects ground rod performance.

This article presents the EMC design techniques for electric vehicle powertrain modules. High voltage EMC regulations for powertrain modules are reviewed first to help understand associated design challenges. The design techniques are then demonstrated in detail to help engineers design a module that will pass the EMC requirements in the test chamber.

Engineers from the Technical University Munich have created a new supercapacitor which is highly efficient and sustainable.

This article discusses the current distribution for the stripline configurations.
