Návrh a realizace obousměrného DC/DC měniče

Abstract

The diploma thesis deals with design and subsequent implementation of a bidirectional DC/DC converter. Theoretical part is an analysis of galvanic insulated inverters together with a description of the function of the peripheral circuit. Practical part deals with the dimensioning and selection of components for the implemented drive, which included a selection of IGBT transistors, exciters, design of medium-frequency transformer, capacitors, chokes, current and voltage sensors, calculation of the power dissipation and cooling. In the next part of the diploma thesis is verification of connection through simulation function in programming environment LTspice. The last part contains description of a laboratory model realized by the bidirectional DC / DC converter with a summary of the results.
