Power Converter for the electric DC arc welding
Vranák, Daniel ; Vorel, Pavel (referee) ; Patočka, Miroslav (advisor)
The main aim of thesis was produce a draft power converters for DC arc welding, which would be suitable for use in regular service. For the purpose of the proposal, first must be acquainted with the possible methods used converters whose distribution and explain the principle place in beginning thesis. Next it was transferred detailed design of individual components, which was used for the construction of the power part of the welder.
