Topic 1. Putting an End to the Bad EMC Design Practices Commonly Employed in Automotive Products.
Many automotive products appear to be intentionally designed to maximize radiated emissions and immunity problems. In fact, product designers often add expensive components that serve no function other than to make electromagnetic interference problems worse. Why does this happen? One reason is that there is a lot of bad design advice coming from companies that sell components for EMI control. Another reason is that many engineers confuse ground with current-return and think that being electrically balanced is always better than the alternative. This presentation discusses these important concepts and highlights some of the design advice from component manufacturers that causes products to fail to meet EMC requirements.
Topic 2. Automotive International EMC Standards Review.
This presentation will review the current revisions of the main international automotive component and full vehicle standards, including CISPR 12, CISPR 25, ISO 11451-2, ISO 11452-2, and ECE Reg. 10.6. We will also briefly touch on the newly published CISPR 36. Attendees will learn how the increasing prevalence of electric vehicle variants has resulted in the addition of sections specific to these vehicle types. The presentation concludes with a look at some of the different facility setup and validation requirements of the standards.
