Noise

EMC testing laboratories often have limitations (limited availability, lead times, etc.) that can make it difficult to obtain timely results from routine troubleshooting. Inexpensive test equipment can support efficient and economical in-house EMC troubleshooting.

This article focuses on PCB layout considerations and the design of the reference return paths for the one- and two-layer boards.

Don’t overlook the fact that EMI filters can be used to prevent unwanted RF noise (such as electrical fast transient burst, conducted RF, and some surges) from entering susceptible devices.

DC-DC converters are among the most important modules in an electric vehicle. In this article, we offer three recommendations to address design aspects of DC-DC converters that will make a huge difference in their EMC performance.
