Welding inverter
 Lizúch, Ján ; Vorel, Pavel (referee) ; Martiš, Jan (advisor)
The aim of a masters thesis is to design components, circuits and to build welding power source. Description and technological process of welding, arc characteristic and welding methods requirements are included in a first part of the thesis. Switching mode power supply topologies are characterized in a next part of the thesis. At the end of a theoretical part, the parameters of welding power source are determined. Its design is described in the next parts of the thesis where calculations and design process of electrical part is described. There are also schematics of circuits shown. In each power part is power dissipation calculated, what is needed to design cooling. Practical build and tests of welding power source are described in the last part of thesis. Measured waveforms and thermal camera images during load test are included in the last part as well
