Speaker

Reinhard Herzer, Semikron Eletronik GmbH & Co.KG, Germany
Herzer_klein.jpg  Reinhard Herzer studied Electrical Engineering and received 1984 his PhD in the field of Microelectronics and 1992 his Habilitation in the field of Power Devices and Smart Power ICs from the Ilmenau Technical University. He joined Semikron Electronics Nuremberg, Germany in 1995 as head of the MOSFET, IGBT and IC research department. Here he is responsible for the introduction of new power device generations as well as driver- and sensor- IC in new power modules and systems. Further he is Associated Professor at the Technical University of Ilmenau were he teaches and coaches students and PhD students.
