Vehicle Electronics

Fraunhofer IISB takes a leading position internationally in the field of power electronics for electromobility. This is evident from the numerous development projects with all large automotive manufacturers and suppliers. Many of the results have gained international attention.

We permanently strive to open up new applications and functionalities. The grid integration of electric vehicles for instance will gain more and more importance in the future. For avionic applications the new possibilities of modern power electronics will pave the way towards the “more electric aircraft”. This means powering many more actuators electrically in order to improve the overall fuel economy, and to reduce the maintenance efforts associated with hydraulic systems.

The EMC lab offers a wide range of services, from tests on prototypes over consulting in case of EMC problems, measurements according to harmonized standards to very detailed circuit and layout optimizations.

ZEPOWEL @ Fraunhofer IISB

Towards Zero Power Electronics - Electronics with lowest energy consumption

With the "Smart Fabrication" demonstrator, an intelligent, cognitive DC/DC converter is being built from the developed power modules within the "Toward Zero Power" project. With this, novel DC voltage networks for industrial applications can be realized.  The converters control the energy flow between the different energy sources, energy storage devices and consumers and ensure a stable supply network.
