This article will discuss electromagnetic-interference (EMI) mitigation techniques as they relate to the optimum performance of vehicle system architectures. Critical areas in vehicles can be highly affected by EMI and lead to subpar electronic circuit performance, especially in automotive power supplies, which are at the heart of an overall vehicle electrical/electronic system.
Covered here will be EMI filtering and other system techniques that can be integrated into the system architecture to minimize RF EMI interference, both conducted and radiated. These should help designers pass EMI standards testing in their respective regions.
