Abstract: This paper presents the results of the modeling and comparison of parallel structures of DC-DC converters for application in wind energy conversion systems with low power. Three different topologies with boost capabilities are studied: boost, non-inverting buck-boost and SEPIC converter. The simulation models are created using a Matlab/Simscape environment. Waveforms of currents and voltages in the circuits are analyzed. Current and voltage stress of the components in different converters are compared. The problem of operation of both converters in the structure with non-equal duty ratios is also considered.
