Two of the most commonly exercised standards for electromagnetic compatibility (EMC) by automotive engineers are CISPR 12 and CISPR 25. While CISPR 12 is imposed as a regulation to ensure uninterrupted communication for off-board receivers, CISPR 25 is often applied to ensure the quality of services of on-board receivers. Performing these tests becomes challenging until the vehicle is prototyped which may prolong the production time in case of failure or need for modification. However, conducting these tests in a simulation environment can offer more time and cost-efficient ways of analyzing the electromagnetic environment of automotive vehicles. In this paper, a computational approach is proposed in order to predict electromagnetic disturbance from on-board electronics/electrical systems using 3D computational electromagnetic (CEM) tool; Altair Feko. The presented study elaborates on radiated and conductive emission simulations performed for both vehicular and component/module level EMI testing according to CISPR 12 and 25. A high-frequency dynamic circuit network of a DC wiper motor is considered as a source of emission while different receiving antennas have been used according to regulation. A study is also conducted by analyzing effects of different types of cable harness on radiated and conducted emission.

Biography:

Fletcher Turner is an Electrical Applications Engineer at TrueInsight. He studied Electrical Engineering and German at the University of South Carolina in Columbia, SC, where he lives and works. In graduate school, he worked in a lab that had research interests in several areas of mechanical and electrical engineering. His major interest was in intelligent control, and developed new algorithms and integrations with neural networks to fuse camera and sensor data for autonomous vehicle navigation. Fletcher has worked with optimizing camera data received from several cameras stationed at different locations, intelligent predictive maintenance, and anomaly detection in robotics. His love of new and exciting applications of engineering is what led him to become an applications engineer, where he can interact with a new field or sub-field almost every day! His passions and hobbies outside of his professional life include spending time with his family (and dogs), travelling the country and globe, and watching all of the Oscar-nominations each year.
