Abstract
U diplomskom radu su opisani svi dijelovi istosmjernih pretvarača i njihov parazitski utjecaj. Objašnjen je princip rada rezonantnih LLC pretvarača, njegovo kapacitivno i induktivno područje rada, te razlozi njegovog rada u induktivnom području i sklapanja pri nultom naponu, a također su prikazane i prednosti i mane. Prikazani su dijelovi i karakteristike transformatora, te gubici u jezgri i namotu transformatora, a također je objašnjen i način upravljanja pretvaračem. Izrađen je proračun transformatora i rezonantne zavojnice u svrhu njihove izrade i ugradnje u model za testiranje ispravnosti rada. Nakon izrade transformatora i rezonantne zavojnice, obavila su se mjerenja i snimili valni oblici, te se vršila usporedba s teorijskim vrijednostima. Objašnjena su odstupanja od teorijskih vrijednosti i prikazani su elementi na kojima dolazi do disipacije snage koja dovodi do slabije učinkovitosti LLC pretvarača.
Abstract (english)
All the parts of the DC converters and their parasitic influence are described in the graduate thesis. The operating principle of resonant LLC converters, its capacitive and inductive region operation, and the reasons for its operation in the inductive region and zero voltage switching are explained, and the advantages and disadvantages are also illustrated. The components and characteristics of the transformer are shown, as well as the losses in the core and the transformer winding, and also the mode of converter control is explained. A calculation of the transformer and the resonant inductor was made for the purpose of their design and integration in the model for operation testing. After making the transformer and resonant inductor, measurements were performed and waveforms were shown, and comparison was made with theoretical values. The deviations from the theoretical values are explained and the elements that are dissipating power which leads to weaker efficiency of LLC converter are identified
