Research Field Power Electronics
The improvement of dynamics, efficiency and signal quality of power electronics in drive applications of mechatronic systems is the primary focus of this research field. This is achieved by using fast switching power semiconductors based on gallium nitride and silicon carbide. Modern semiconductor technologies enable highly efficient operation at DC link voltages of up to 800V at switching frequencies >100 kHz.

High-efficient power electronics
The optimization of highly integrated power electronic systems is realized with respect to their electromechanical, thermal and electrical properties. For efficient and fast switching, parasitic inductances and capacitances of the circuit layout are minimized. Heat dissipation of power semiconductors is accomplished via highly thermally conductive but electrically insulating materials. Analog filters at the output of switched circuits increase signal quality and suppress high frequency noise. Leading simulation tools in the field of FEM and circuit simulation are used for the circuit designs.
