Two-quadrant regulated power supply for laboratory purposes
Kalus, Jiří ; Vorel, Pavel (referee) ; Knobloch, Jan (advisor)
The main goal of the bachelor´s thesis is a suggestion of switching power supply with energy absorption for the case of two-quadrant load. The source includes of three parts: the power for the control circuit, single-converter and absorber of the recovered energy. Output power source is 400 W and output voltage 0 to 40 V, current +10 / - 10 A. This bachelor´s thesis deals with the first half of the circuit description and the second part there are analysis and the suggestion. Scheme and printed circuit cards are in attachment.

Converter for DC Welding
Siuda, Petr ; Vorel, Pavel (referee) ; Patočka, Miroslav (advisor)
This master´s thesis with the peripheral and structural design of power converter that will be used for DC welding. The drive itself is based on the principle of two single-acting permeable converters operating in counter strokes to a mutual load. The inverter operates at a frequency of 60kHz, and its output current can be controlled from 0 - 100A. Welder is equipped with a variable constant current or power adjustment. The device is powered from a single-phase 230V.
