Dr. Joachim Holtz

Joachim Holtz graduated from the Technical University Braunschweig, Germany, in 1967. He received his doctorate degree two years later from the same university.

He became Full Professor of Electrical Engineering in 1971.In 1972 he joined the Siemens Research Laboratories in Erlangen, Germany. His research on high-power thyristor PWM inverters resulted in the invention of the first three-level inverter. In 1973 he became Head of the Research and Development Group New Traffic Technologies. He developed the linear synchronous motor concept for magnetically levitated high-speed trains. He invented a speed sensorless drive control system for this motor and designed a magnetic guidance system for levitated trains.

Dr. Holtz has published more than 100 technical papers including 60 refereed publications in journals; he has published 10 invited conference papers and 4 invited papers in journals. He has earned four IEEE prize paper awards. He is the coauthor of four books, and has been granted 27 patents.

In PEPQA Dr. Holtz will talk about:

Dr. Elemer Sorrentino

Electrical Engineer (Cum Laude, 1984) and Master (Honors, 1986) degrees from Universidad Simón Bolívar (USB, Caracas, Venezuela), and the PhD degree (Cum Laude, 2014) from Universidad Carlos III de Madrid (Spain). Since 1984, he has been a professor at USB and a consulting engineer for several companies.
Author of more than 150 articles published in conference proceedings or in scientific journals. His research interests are in power system protection, power system analysis, and electrical machines. His experience in electrical protections includes carrying out coordination studies of protections for the electrical, oil, petrochemical, cement and steel industries, as well as the design, installation, and start-up of computerized protection devices, and the execution of special and routine tests on protection relays and switches for low voltage.
