Abstract
Electromagnetic disturbances from power electronic systems can affect communication networks, especially in the automotive wiring harness with its limited distance between wires. The introduction of Wide-Band-Gap (WBG) semiconductors in power electronic systems enables smaller components and higher efficiency due to higher frequencies and steeper slopes of the PWM control signals. Furthermore, the increasing energy demands lead to a raise of the voltage level up to 48 V. In contrast to high voltage automotive systems with complex shielded cables for EV (Electric Vehicles), unshielded cables are applied in 48 V cabling systems. The use of fast switching power electronic devices in combination with the increased voltage level pose a new challenge on electromagnetic compatibility in automotive environment. This paper shows investigations on the immunity of communication networks under these new conditions. Therefore, measurement and simulative analysis are presented to estimate the potential impact on the reliability of data transmission.
