Power supply with current reversal
Hrdina, Adam ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
This thesis describes the design of regulated power supply that allows the reverse direction of the current. The supply can as well work as an electronic load. The supply has continuous settings of voltage from 0 to 50 V and continuous settings of maximum current from 0 to 5 A. The first part of thesis consist general description of power supply and of electronic load. The second part then includes the main design of overall concept of the supply and design of individual components.

Multipurpose power supply for electroplating system
Pinďák, Michal ; Vorel, Pavel (referee) ; Procházka, Petr (advisor)
The aim of the bachelor thesis is the practical proposal of the multipurpose power supply for the electroplating system. The individual technological processes of electroplating, for which the parameters of the source have to be adapted, are presented in the theoretical part. This part includes the entire division of pulse DC/DC converters without a transformer from the aspect of working quadrants and finally the ways of their controlling. There is also introduced the analysis of parameters of the presumed DC power supply XP Power HDS3000PS60. The conclusion of the thesis is focused on the entire proposal of converter wiring, its construction and subsequent commissioning through the software LabVIEW.

Laboratory power source
Lízner, Václav ; Marcoň, Petr (referee) ; Szabó, Zoltán (advisor)
This bachelor thesis deals with the complete design and realization of the laboratory DC power source. There is designed a power supply with adjustable output voltage from 0 to 30V and with adjustable current limiter up to 3A. All output values are analog controlled, the microcontroller is used only for the voltage and current measuring. This data is shown on the LCD display. The thesis includes also participation of the DC sources, what is focused on the basic wiring of the switching DC sources.

Switch-Mode Power Suplies for Electronic Circuits
Hantl, Josef ; Steinbauer, Miloslav (referee) ; Murina, Milan (advisor)
This bachelor’s thesis deals problems with Switching Power supplies and their comparison with classical power supplies. In this project, functions of basic kinds of convertors for Switchmode supplies and their characteristics, are explained. It adverts to possibilities improving of effectivity of power supplies by using resonant and quasiresonant convertors in switching supplies. The thesis designs a circuit conception, detailed perimeter design of Switchmode supply and contains simulation this circuitry. One part of this project are details for realisation power supply (drawing printed circuit, list of used materials).

Trilobot Upgrade
Polášek, Patrik ; Hrubý, Martin (referee) ; Rozman, Jaroslav (advisor)
The main aim of this work is to create a robot moving on wheels, create communication among all the sensors and microcomputers with the help of the Robot Operating System (ROS). Sensors are mounted on a plastic handle that is printed on 3D printer. The Arduino microcomputer manages low-level signals for reading sensor data and signals to control the engine, the another one and more powerful ODROID-XU4 microcomputer runs the core of ROS and a graphical application that allows controlling robot on the touchscreen.
