Pspice libraries development for EMC analysis

In order to perform EMC design activities, engineers need to have some tools for preliminary risk analysis to determine filters needs and/or architecture orientation choices. Huge variations in term of requirements between different carmakers can be observed (40 dB difference for example for a simple conducted emission test can be observed between OEMs). The product nature that we develop can be also very different (from small cameras to DC/DC converter for Electric Vehicle applications). As a consequence we decided to develop simulation capabilities based on Pspice, instead of using generic rules or simple return on experiences to design our products. This paper provides a synthesis of these capabilities, for emission, immunity and ESD testing, focusing on the latest modeling techniques developed for these different aspects.
