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.


Drive Inverters & Mechatronics

We are working on innovative integration concepts as well as on new device, interconnection, and cooling technologies that foster a 3D integration, increase ruggedness, and decrease costs of power electronics.


Battery Chargers

We provide on-board battery chargers (AC/DC converters) in the range from 3.7 to 22 kW for plug-in and pure electric vehicles, as well as DC battery chargers (DC/DC converters) in the range of 3 kW and much higher for ultrafast, high power applications.


DC/DC Converters

We provide custom specific DC-DC Converters for automotive, aircraft and stationary applications.


Inductive Power Transmission

We develop and realize complete inductive power transfer systems. From the FEM-Simulation, over power electronics analysis/simulation and mechanical integration to complete prototypes.


Device Characterization

With our comprehensive test facilities, we evaluate the potential of new active or passive components in close coordination with you. We also offer to convert measurements into powerful simulation models for your virtual prototype.
