САЖЕТАК / ABSTRACT:
U modernim aplikacijama postoji sve veća potreba za uštedom teških materijala poput gvožđa i bakra. Od uređaja energetske elektronike, koji predstavljaju sastavni deo savremenih sistema, zahteva se visok stepen integracije, što povlači rad na visokim prekidačkim učestanostima. U ovom radu predstavljena je procedura za projektovanje i ispitivanje visokofrekventnog transformatora. Procedura po koracima obuhvata odabir optimalnog feromagnetskog materijala i oblika magnetskog kola, poprečnog preseka provodnika, licni i precizno modelovanje gubitaka. Rezultati proračuna su verifikovani pomoću softverskog paketa Finite Element Method Magnetics – FEMM 4.2. Dalje, izvršeno je projektovanje prototipa monofaznog visokofrekventnog transformatora jediničnog prenosnog odnosa. Eksperimentalnim testiranjem u laboratorijskim uslovima dobijeni su parametri zamenske šeme transformatora. Transformator je uspešno implementiran u sklopu prototipa bidirekcionog rezonantnog LLC pretvarača, pri aplikaciji Solid State Transformer. Na kraju, date su sugestije i predlozi za dalji istraživački rad na temu modifikacije predstavljene procedure pri projektovanju planarnog transformatora sa ciljem postizanja većeg stepena hardverske integracije.
