Abstract

The diploma thesis deals with a design of power part of reversible DC/DC converter. In the theoretic part, firstly there is an analysis of topologies for bidirectional energy transfer in renewable energy systems with accumulative units. Then there are introduced various solutions of circuit connections of reversible DC/DC converters both non-isolated and isolated. In the practical part, there is a design of a specific circuit of reversible DC/DC converter. The function analysis of the converter and subsequent dimensioning and selection of components for realization is carried out. The dimensioning of power part includes a design of impulse transformer, cooling , selection of suitable drivers, transistors and other components. The function of the specific DC/DC converter is verified with simulation software OrCAD PSpice during both directions of energy transfer and different parameters. 3D model of designed converter is created for vizualization.
