At the Institute for Drive Systems and Power Electronics (IAL), experts for electrical machines, power electronics and drive control are doing research work in the entire field of drive technology reaching from the microwatt to the multi-megawatt range. A unique feature of IAL in the German-speaking part is the close co-operation of two full professorships in drive technology united in one institute.

Based on the longtime work of Prof. H.O. Seinsch, Prof. H.-D. Stölting and last but not least  of Prof. H. Jordan, the most well-respected electromechanical engineer in the world of the postwar period, the main research work in the field of electrical machines focuses on the development of calculation methods and software as well as on the research, precalculation and elimination of technically important parasitic effects like magnetically excited noise, torque pulsations or bearing currents.

The competences in the field of power electronics are reaching from the characterisation of power semiconductors and the development of innovative drive concepts, the development, dimensioning and optimisation of power electronic circuits and their respective control and modulation methods to the control of electric drives with or without mechanical sensors.

The joining of the two formerly independent institutes Electrical Machines and Power Electronics to one institute in 2001 reflects the technological development towards integral overall systems. On the one hand, this structure is the ideal basis for a close co-operation , and on the other hand, it offers distinct expertise in both chairs.
