Electromagnetic Simulation Applied to Automotive EMC Testing

The process of designing and testing vehicles for EMC compliance can be long and expensive. Electromagnetic simulation allows potential compliance issues to be identified early in the development process, before the construction of prototypes. However, it is desirable that the simulation is able to model the test setup accurately. In this article we look at the set-up of a virtual EMC test chamber using a commercially available software and compare the simulated results to measurements from a General Motors automotive EMC test.

Electromagnetic Analysis of Cable Harnesses in an Automotive Environment

1405 F3 coverThis article shows how electromagnetic simulation tools can be used to investigate effects of high-speed signals in cable harnesses in a vehicle: cross talk, radiation and interference with a receiving antenna. Results are presented for two types of digital sequences and compared with standards. Cable shielding is designed to be adequate without adding unnecessary weight.
