EMI (electromagnetic interference) mitigation is a critical step in the design process in most electronic systems, and especially so in the automotive world. In many cases, automotive OEM emissions requirements are even more stringent than both national and international standards bodies like the FCC. Unfortunately, by their nature, switching regulators are sources of EMI; but, in order to keep power supply designs small and efficient, switchers are a critical component. So how can you reap the benefits of a switching regulator while still meeting challenging EMI requirements?
Riding Out Automotive Transients : Architecting Front End Power Conversion Stage for Automotive Off-Battery Loads
With rapidly expanding electronic content in latest generation of cars, there is an ever increasing need for power conversion from the car battery rail. The 12-V battery rail is subject to a variety of transients. This presents a unique challenge in terms of the power architecture for off-battery systems. This presentation introduces the different types of transients that occur in automotive battery rails, the causes of those transients, and the standards and specifications defining the test conditions for those transients.
