Napredni 50 kVA dvosmerni aktivni trifazni IGBT AC/AC pretvornik z visoko preklopno frekvenco in visokim izkoristkom : doktorska disertacijaKorelič, JožeDelo uvodoma opisuje znane izvedbe pretvornikov s korekcijo faktorja moči za enosmerni in dvosmerni pretok energije. Prikazane so tipične izvedbe ter poudarjene dobre in slabe lastnosti posamezne ... izvedbe. Nato so predstavljeni parametri in pogoji za napredno izvedbo pretvornika. Postavi se teza, da je potrebno za napredno izvedbo poseči tako v strojno opremo kot programsko opremo. V nadaljevanju je predstavljeno delovanje izbrane konfiguracije aktivnega usmernika. Predstavljen je način vodenja aktivnega usmernika in simulacijska shema z regulacijo napetosti enosmerne zbiralke s poudarkom na optimiranju vhodnih dušilk in kondenzatorske baterije enosmerne zbiralke. Simulacijski model v okolju MATLAB/Simulink služi kot orodje za oceno obremenitve in izbor komponent ter verifikacijo stabilnega delovanja regulacijskih algoritmov. Podrobno je predstavljen eksperimentalni model sistema trifaznega aktivnega dvosmernega usmernika in pretvornika za štirikvadrantno vodenja trifaznega izmeničnega motorja ter prikazan način izvedbe za dosego boljšega izkoristka, povišanje stikalne frekvence, znižanje vplivov na okolje in učinkovitejše hlajenje. Predstavljen je mikrokrmilniški modul s pomočjo katerega se je izvajalo testiranje. V zadnjem delu so predstavljeni rezultati meritev na simulacijskem in eksperimentalnem modelu. Analiza rezultatov zajema oceno doseganja napovedanih lastnosti in morebitna odstopanja ter sugestije za nadaljnje izboljšave.Type of material - dissertation ; adult, seriousPublication and manufacture - Maribor : [J.
