Abstract

U ovom radu analiziraju se ispravljači (AC-DC pretvarači) koji mogu ili služiti samostalno (izravna AC-DC pretvorba), ili kao ulazni krug frekvencijskih pretvarača (dio neizravne AC-AC pretvorbe). Analiziraju se, analitički i simulacijski, diodni i tiristorski ispravljački spojevi prvenstveno sa stanovišta njihovog utjecaja na napojnu mrežu. Ovi spojevi se uspoređuju prema valovitosti izlaznog napona izražene preko pulsnosti napona, također prema faktoru snage i normiranoj tipnoj snazi transformatora. Također se analizira harmonijski sastav struje koju ispravljački spojevi opterećeni induktivnim trošilom vuku iz napojne mreže.

Abstract (english)

In this paper, AC/DC converters, which can be used independently or as a frequency converter input circuit, were analysed. Diode and thyristor rectification circuits were analyzed by analytical and simulation program means, primarily from the point of view of their influence on the power supply network. These converter types are compared muttualy in view of output voltage ripple, also the power factor and the standard power output of the transformer. It also be analyzed the harmonic distortion of the current drawn by the rectifiers with inductive load from the power supply network.
