Abstract
Ovim diplomskim radom prikazan je skin efekt i efekt blizine. Fenomen skin efekta javlja se u strujnim krugovima gdje teku izmjenične struje zbog kojih dolazi do povećanja gustoće struje na površini vodiča, dok je mala gustoća u unutrašnjosti vodiča. Učinkovitost površine poprečnog presjeka vodiča smanjuje se zbog skin efkta. Skin efekt povećava otpor vodiča koji rezultira povećanjem gubitaka samog vodiča. Dubina prodiranja je vrijednost koja karakterizira skin efekt. Ta veličina je ovisna o magnetskoj permeabilnosti, otporu i frekvenciji struje. Skin efekt nastaje međudjelovanjem električnog i magnetskog polja. Fenomen je opisan uz pomoć formula. Pokazan je utjecaj vrtložnih struja koje su prisutne kod njega. Efekt blizine je fenomen koji izaziva nejednoliku proizvodnju izmjenične struje koja se javlja u susjednim vodičima. Uz pomoć simulacije u Ansys-u modeliran je skin efekt kod okruglog vodiča i kod dva paralelna okrugla vodiča kroz koje protječu izmjenične struje u istome i u suprotnome smjeru. U simulaciji se kod dva paralelna vodiča vidi pojava efekta blizine.
Abstract (english)
The paper explores in depth the skin effect and the proximity effect. The phenomenon of skin effect occurs in circuits where alternating currents flow, causing an increase in current density on the surface of the conductor, while the density is low in the interior of the conductor. Due to the skin effect, surface efficiency of the cross-section of the conductor decreases. The skin effect increases the resistance of the conductor, which results in increased losses. Penetration depth is a value characteristic of the skin effect, and it depends on the magnetic permeability, resistance and current frequency. The skin effect is a result of the interaction between the electric and magnetic field. In the paper, the phenomenon was described by the application of specific formulas, and the effect of eddy currents was presented. The proximity effect is a phenomenon which causes nonuniform production of alternating current occurring in adjacent conductors. By making simulations in Ansys, the skin effect was modeled for a round conductor and for two parallel conductors with AC which flows through the conductors in the same and opposite directions. In the simulation, the proximity effect can be observed in the case of two parallel conductors.
