Description	Theoretical and experimental methods will be used to solve prospective ways of energy conversion suitable for modern power systems, drive systems and apparatus with high efficiency and dynamics. Besides a wider spectrum of coupled problems (interaction of several physical fields, where the primary role rests with the electromagnetic field), the theme includes cooperation of electrical, mechanical and other circuits, utilization of modern semiconductor control elements and investigation of behaviour of working media. Also involved is the study of concominant parasitic effects including their elimination. Attention will be also paid to optimizing the utilization of renewable-energy resources (power systems in wind and hydro plants) and environmental aspects of energy conversion,especially in electrical drives. (en) Pomocí teoretických a experimentálních metod bude řešena problematika perspektivních způsobů konverze energie vhodných pro moderní pohonné, energetické a přístrojové systémy vyznačující se vysokou účinností a dynamikou. Tato problematika zahrnuje studium širšího spektra sdružených úloh (interakce několika fyzikálních polí, kde primární roli hraje pole elektromagnetické), otázky kooperace elektrických, mechanických a jiných obvodů, uplatnění moderních polovodičových řídicích prvků a chování pracovních medií. Nedílnou součástí bude i studium doprovodných parazitních jevů a možností jejich eliminace. Pozornost bude věnována také optimalizaci využití obnovitelných zdrojů energie (energetické systémy ve větrných a vodních elektrárnách) a ekologickým aspektům její konverze, zejména v elektrických pohonech.
