Magnetyczne mnożniki częstotliwości – badania naukowe w Politechnice Lubelskiej w latach 1968-2014

W artykule omówiono badania naukowe w dziedzinie magnetycznych i hybrydowych mnożników częstotliwości prowadzone w latach 1968-2014 w Politechnice Lubelskiej. Przedstawiono osiągnięcia w dorobku naukowym pracowników oraz wybrane wdrożenia przemysłowe zaprojektowanych rozwiązań.

In most cases, magnetic frequency multiplier structure does not differ much from a plain transformer. However, there are many differences in their operation and the problem of optimization of these devices is very extensive. Despite the relatively long history of the idea of magnetic frequency multipliers, their intense development as the high-power devices fell on the period of the second half of the twentieth century. The article describes scientific research in the field of the magnetic and hybrid frequency multipliers carried out in the years 1968-2014 at the Lublin University of Technology. The team of scientists led by Professor Tadeusz Janowski built and tested several magnetic frequency convertors. The large number of them has been successfully applied in industry. Eight PhD dissertations have been prepared, five postdoctoral dissertations (habilitation theses) and over hundred scientific papers in the subject of frequency multipliers have been published. Advances in the field of high power semiconductor converters has led to the marginalization of purely magnetic solutions.
