Josef Lutz (electrical engineer)

from Wikipedia, the free encyclopedia

Josef Lutz (* 1954 in Ellwangen (Jagst) ) is a German physicist and electrical engineer .

Career

Lutz studied physics at the University of Stuttgart and from 1983 worked at Semikron Electronics in Nuremberg, where he first worked on the development of GTO thyristors . He later shifted his focus to the field of fast diode development , in which he held a number of patents and introduced the Controlled Axial Lifetime Diode (CAL diode). In 1999 he received his doctorate in electrical engineering from the University of Ilmenau . Since August 2001 Lutz has been professor for power electronics and electromagnetic compatibility at the Technical University of Chemnitz .

In 2005 he was made an honorary professor by the Stavropol University of Technology .

Scientific work

Lutz is considered an expert in the field of chip production. The research focus of his professorship is on the reliability of semiconductor power components, in particular with regard to their use in electromobility. The research is also directed towards future-oriented semiconductor materials such as SiC and GaN .

Courses

Semiconductor physics is examined intensively in his lectures . Based on this, the functionality and properties of power electronic components are dealt with. In the next step, complex systems such as B. DC-DC , AC-DC and DC-AC converters, explained and calculated in detail. Finally, the influence of the systems on one another is examined, with electromagnetic compatibility being just one focus.

Union activity

Lutz has been a member of IG Metall since 1983 and works as a speaker at information events. Tensions arose in 1999 when the collective agreements favored by the union were rejected by Lutz and others, prompting Semikron to convert temporary positions into permanent jobs.

Private astronomical research

In addition to his research in the field of electrical engineering, Lutz is privately involved in astronomy and questions the theory of the Big Bang , which is largely established and accepted by physicists and astronomers to this day. Based on the discovery of the Great Wall , he published a book on his criticism in the Neuer Weg publishing house in the early 1990s . In 2005 he was a speaker at the 1st Crisis in Cosmology Conference , the daily volume of which was published by the American Institute of Physics .

Private life

Josef Lutz is married and has two children.
