Research

Power electronics, and static power conversion in general, is an engineering discipline that was introduced into practice at the beginning of the 20th century. Today, at the beginning of the 21st century, power electronics is part of our daily lives. We can find them in almost all applications; household appliances, automotive, multimedia, ICT, industry, transport, military, aerospace, etc. Wherever and whenever we need to control a power/energy flow without significant losses, we cannot avoid the use of power electronics. It is almost impossible to imagine life today without power electronics. Every area of life will be different. Power electronics and static power conversion have contributed significantly to the global economy. The invention of the IGBT has contributed more than US$18 trillion to the global economy. Power electronics and power semiconductors in general have contributed much more.

The Innsbruck Power Electronics Lab (i-PEL), as part of the Institute of Mechatronics, was founded by Infineon Technologies AG, Austria and the University of Innsbruck. The research activities are mainly focussed on state-of-the-art power semiconductors and power electronics in general.
