Cable Antennas and Ferrite Cores

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 in Electric Vehicles

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.

Capacitors: Theory and Application

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.

EMC Design Techniques for Electric Vehicle Powertrain Modules

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.
