Abstract

Electromagnetic compatibility (EMC) has become much more important especially over the last decade due to incorporating advanced driver assistance and electric propulsion systems into conventional vehicle architecture. Electromagnetic shielding is a conductive barrier used for protecting electronic circuits against external electromagnetic interference (EMI). Shielding effectiveness (SE) is a measure of shielding performance against an interfering electromagnetic source. Design limitations inside electric vehicles (EV) forces to investigate on increasing SE without changing the shielding enclosure dimensions. Graphene is widely used in many studies due to its good conductivity and strong structure. In this study, a numerical model for a shielding enclosure in which inner surfaces are coated with graphene sheets, is designed. The effect of different aperture shapes on SE is analyzed according to coating different inner surfaces of the enclosure with graphene sheets.

Özet

Elektromanyetik uyumluluk (EMC), özellikle son on yılda gelişmiş sürücü destek ve elektrikli tahrik sistemlerinin geleneksel araç mimarisine dahil edilmesiyle çok daha önemli hale gelmiştir. Elektromanyetik ekranlama, elektronik devreleri dış elektromanyetik girişimden (EMI) korumak için kullanılan iletken bir bariyerdir. Ekranlama etkinliği (SE), girişim yapan bir elektromanyetik kaynağa karşı ekranlama performansının ölçüsüdür. Elektrikli araçların (EV) içindeki tasarım sınırlamaları, ekranlama kutusu boyutlarını değiştirmeden SE'yi artırmayı araştırmaya zorlamaktadır. Grafen, iyi iletkenliği ve güçlü yapısı nedeniyle birçok çalışmada yaygın olarak kullanılmaktadır. Bu çalışmada, iç yüzeyleri grafen plakalarla kaplanmış bir ekranlama kutusu için nümerik model tasarlanmıştır. Farklı açıklık şekillerinin SE üzerindeki etkisi, kutunun farklı iç yüzeylerinin grafen plakalarla kaplanması durumlarına göre analiz edilmiştir
