Abstract

U radu je opisan kondenzator, superkondenzator i superkondenzatorski slog. Navedena su svojstva svakoga od njih i opisani nedostatci. Objašnjen je problem razlika napona ćelija superkondenzatorskog sloga i njegove posljedice. Dan je pregled dviju vrsta metoda za upravljanje energijom koje rješavaju spomenuti problem: disipativne i nedisipativne. Razrađena je metoda upravljanja energijom uz prespojnu matricu i jedan dvosmjerni pretvarač. Model je izrađen u MATLAB-ovom paketu Simulink te su kao rezultat dani grafovi uz objašnjenje.

Abstract (english)

The paper describes a capacitor, a supercapacitor and a supercapacitor stack. The features of each of them are listed and the disadvantages are described. The problem of voltage differences of supercapacitor cells and its consequences is explained. An overview of two types of energy management methods that solve the mentioned problem is given: dissipative and non-dissipative. An energy management method with a switch matrix and one two-way converter is elaborated. The model was made in MATLAB's Simulink package and as a result graphs were given with an explanation.
