Simulations and experiments for EMC compliance in automotive environment

The development and testing of automotive (sub)systems, particularly for Electromagnetic Compatibility (EMC) usually requires expensive test facilities. This paper describes the use of electromagnetic simulation to demonstrate the level of confidence that can be placed in measurements taken in more general laboratories, thus giving an estimate of the accuracy these facilities can provide. This is important in order to enable/allow more developments in automotive systems from research and development teams without standards compliant test facilities. The results are compared with full wave simulations and show that such EMC analysis can be undertaken with a reasonable estimation of accuracy and providing a framework for pre-compliance or developmental testing
