An AM radio can be useful for finding both radiated emissions and ESD events. Understanding how radio works is essential for engineers to use this low-cost technology to troubleshoot complex EMI issues.
Implementing a process of EMC compliance for a specific project is much more than simply ensuring that the design engineers follow a long list of “do’s and don’ts” in the form of EMC design rules. Following this process will reap benefits when EMC performance is evaluated at the end of the design process.
In this column, the author offers a brief summary of a more systematic approach for using ferrite cores on cables. This summary can serve as a “ferrite core checklist” for design and test engineers.
Low-frequency magnetic fields, a type of electromagnetic disturbance commonly found in electric vehicles, can pose potential health hazards to humans and affect the operation of critical EV components. Here are some design techniques to help mitigate the problem.
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.
This article presents the fundamentals and application of capacitors. What is a capacitor, and how do we select them? Techniques of selecting capacitors and things to consider when using capacitors are highlighted. Both practical examples and simulation are used to demonstrate the key points.
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.
