Technical University "Gh. Asachi" of Iasi

Faculty of Electrical Engineering

Background

I have graduated as M.Sc.:

Electrical Engineering from “Gh.Asachi” Technical University of Iasi, in 1972.

 I became assistant professor in 1972 - 1980, lecturer in 1980 - 1990, associate professor in 1990 - 1996 and professor in 1996  at the Electrical Engineering Faculty of Iaşi, Department of Energy Utilization, Electrical Drives and Industrial Automation.

I get the Ph.D. degree in 1983  with the thesis entitled "The studies for possibilities by regulation of speed the systems by drives with induction linear motors" at “Gh.Asachi” Technical University of Iasi.
