Power Converter for the electric arc welding
Jaša, Jakub ; Vorel, Pavel (referee) ; Patočka, Miroslav (advisor)
This thesis deals with the peripheral design, construction design and implementation welder DC arc. The concept of welder is based on the use of two single action forward converter working-pull. Converters operate at a frequency of 60 kHz. Output current can be adjusted in the range from 0 to 140 A. After switching function the welder can operate as a battery charger. Charging current can be adjusted in the range of 0-70 A. The device is powered from a single phase supply 230 V.

Current source for measuring purposes
Chevalier, Stanislav ; Vorel, Pavel (referee) ; Patočka, Miroslav (advisor)
Goal of this semestral thesis is to design power converter which is to be used for measurement. The converter consists of two forward converters in push-pull topology. The converter is to behave as a constant current source with maximum open-circuit voltage of 1000V. Maximum current is 5A. The current range is split into three sub-ranges, to meet the strict requirements on ripple current. The range of currents is 0-5A. The operating frequency of converter is 34KHz. The converter will be charged using two portable electric generators with output voltage 230V.
