Parasitic Capacitance

Grounding is often viewed from separate points of view - safety, ESD, or EMI.  This article combines all these aspects together so that practitioners can address grounding at the factories and in the laboratories in a comprehensive way.

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.

Resonance phenomenon is explained using several common decoupling capacitor configurations.

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.
