Simulation tools for modeling and simulating power converter circuits

U radu se opisuje analogni simulator učinskih pretvaračkih spojeva Terel Tergane 78. Na simulatoru se obrađuju osnovni pretvarački spojevi temeljeni na jednofaznom mosnom spoju za ispravljanje, izmjenjivanje te istosmjernu pretvorbu električne energije. Provode se eksperimenti navedenih spojeva te opisuju njihova svojstva i ponašanje. Isti spojevi se modeliraju i simuliraju računalnim simulacijskim programom PLECS. Provodi se komparativna analiza osnovnih karakteristika korištenih simulatora sa gledišta modeliranja, simuliranja i analize ponašanja pretvaračkih spojeva. The paper describes an analog simulator of power converter circuits Terel Tergane 78. The simulator deals with basic converter connections based on a single-phase bridge circuit for rectification, inverting and direct conversion of electricity. Experiments of these compounds are performed and their properties and behavior are described. The same circuits are modeled and simulated by the computer simulation program PLECS. A comparative analysis of the basic characteristics of the used simulators from the point of view of modeling, simulation and analysis of the behavior of converter compounds is performed.
