The packing densities of electrical and electronic components in modern control systems, production equipment, in airplanes and vehicles and in data-processing facilities are increasing. Spatial proximity of electronic components, constantly-rising cycle and data rates in digital components and cable-connected communications systems, increasing cycle rates for switched power electronic modules, and almost complete utilization of the frequency spectrum up to the GHz range for wireless communication applications: all of these give rise to growing problems regarding mutual interference when electromagnetically coupling electrical and electronic components and devices.
The focus of the work conducted by the Eletromagnetic Compatibility research group at Ulm University of Applied Sciences is firstly on the EMC of bus and wireless systems for transmitting high data rates in the vehicle (FlexRay, Ethernet, LVDS, USB, Wi-Fi, Bluetooth, …). Due to the high packing density of electronic systems and the associated cable harnesses in the vehicle, the signal integrity, the integrity of the supply system and the control of the electromagnetic coupling mechanisms is still a huge challenge for these kinds of systems. Secondly, the increased use of electric drives in the vehicle gives rise to new types of interferences. Controlling these will play an important role in future applications – especially for the appropriate design of entire-vehicle electronic systems. Although in recent years the group's research was concentrated on investigating expected interferences and coupling paths, current and future work focuses on interference suppression measures and system concepts for the coexistence of electrical drive systems and electronic systems in the vehicle.
