| Abstract | U ovom radu snimljeni su bifurkacijski dijagrami i valni oblici struje prigušnice, napona
rampe i ulaznog napona za karakteristična ustaljena stanja istosmjernog silaznog pretvarača
napona 7V, 10W, istosmjernog uzlaznog pretvarača napona 25V, 25W te istosmjernog uzlaznog
pretvarača napona 27V, 15W pomoću programske podrške WaveStar i Matlab. Opisan je sustav
za snimanje bifurkacijskih dijagrama, njegove prednosti i nedostaci te je izvršena usporedba sa
sustavom korištenim u prijašnjim radovima. Iz dobivenih bifurkacijskih dijagrama i prema
redoslijedu ustaljenih stanja prepoznat je put u kaos. Utvrđeno je da kvaliteta bifurkacijskih
dijagrama snimanih sustavom opisanim u radu uvelike ovisi o istosmjernom izvoru napajanja i
njegovim mogućnostima. |

| Parallel abstract (English) | Bifurcation diagrams and waveforms of choke current, ramp voltage and input voltage for
characteristic steady-states of the buck converter 7V, 10W, boost converter 25V, 25W and boost
converter 27V, 15W are obtained by using WaveStar and Matlab software. The system for
obtaining bifurcation diagrams, its advantages and disadvantages are described and comparison
between system described in this paper and system used in previous papers is performed. From
obtained bifurcation diagrams and according to order of steady-states route to chaos is
recognized. It is established that the quality of the bifurcation diagrams obtained with system
described in this paper greatly depends on the DC power source and its capability. |
