DESPRE AUTOR

EMIL TUDOR – S-a nascut in 21.06.1969 in Buzau. Este doctor in inginerie electrica al Universitatii „Politehnica” din Bucuresti, Romania, din anul 2006.

Cercetarile initiale au fost realizate in cadrul companiei ICPE SAERP S.A. Bucuresti, unde a evoluat de la inginer la cercetator senior, cu rezultate in dezvoltarea si producerea echipamentului de tractiune pentru vehicule electrice (30 de prototipuri de troleibuze si tramvaie).

Principalul sau rezultat de cercetare a fost proiectarea unei unitati de control electronic pentru vehicule precum tramvaiul, troleibuzul si autobuzul electric. Din mai 2017 a fost promovat in functia de director general al ICPE SAERP S.A. Incepand cu luna iunie 2018 este sef al Laboratorului de Masini si Actionari Electrice din INCDIE ICPE-CA Bucuresti. A publicat peste 60 de lucrari stiintifice, trei carti si 16 brevete privind echipamentele de tractiune pentru vehicule electrice. Este Membru Corespondent al Academiei de Stiinte Tehnice din Romania – Sectia 3 Electrotehnica si Energetica. Este membru al: European Power Electronics and Drives Association (EPE); IEEE Senior Member si al Asociatiei Generale a Inginerilor din Romania (AGIR).

Emil S. TUDOR was born on 21.06.1969 in Buzau. He is PhD in electrical engineering at the „Politehnica” University of Bucharest, Romania, since 2006.

The initial research was carried out at ICPE SAERP S.A. Bucharest, where he progressed from engineer to senior researcher, with results in the development and production of traction equipment for electric vehicles (30 prototypes of trolleybuses and trams). His main research result was the design of an electronic control unit for vehicles such as trams, trolleybuses, and electric buses. Since May 2017, he has been promoted to the position of General Manager of ICPE SAERP S.A. Starting in June 2018, he has been head of the Laboratory of Machines and Electric Drives at INCDIE ICPE-CA Bucharest. He has published more than 60 scientific papers, three books, and 16 patents on traction equipment for electric vehicles. He is a Corresponding Member of the Romanian Academy of Technical Sciences – Section 3, Electrotechnics and Energy. He is also a member of the European Power Electronics and Drives Association (EPE), an IEEE Senior Member and a member of the General Association of Romanian Engineers (AGIR).
