Title: Porównanie trzech przekształtników 24-pulsowych z autotransformatorem o różnym połączeniu
Abstract: In this paper, the comparison of star, polygon and zigzag connected autotransformer based 24-pulse AC-DC converters has been presented. They are12-pulse rectifiers incorporated pulse doubling DC ripple re-injection technique supplying VCIMD or DTCIMD load. Simulation results indicate that lower capacitances result in more deterioration in power quality indices at ac mains. In this case, VCIMD has a bitter impact than DTCIMD. Also, using polygon and star connection autotransformers result in lower voltage and current distortions respectively.
Key words: przekształtnik wielopulsowy, .autotransformator.
