DC/DC converter 12V/300V
Žurek, Jan ; Hanák, Pavel (referee) ; Kubánek, David (advisor)
This Bachelor´s Thesis is about switch power supplies theory. It contains comparation with power supplies made of linear components and briefly describes principals of each type. Bigger attention is devoted to fly-back engagement, on which´s basic is then in practice designed particular switch power supply. All key components are counted, including initiation of important species interaction, especially of transformator, MOSFET semiconductor triode, output diode, and there are chosen important components, which are subsequently implemented into the particular switch power supply engagement. This blocking engagement turned out to be functionless. That was why I decided to use engagement called half-bridge, which was viable.

Laboratory source based on switching technology
Kočí, Martin ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
The aim of this thesis is a description of the dierent topologies used in switching power supply and subsequent use of acquired knowledge to select an appropriate topology, power supply, using the selected topology and the subsequent construction of laboratory source as a whole. Ideological content of the proposal are part of the power source based on the topology being used in switching power supplies, also on the controller working as buck converter controlled by PWM and the control section, whose mainfeature is the 8-bit microprocessor. The design is shown working with the designprogram PXLS Expert and the program for PCB Design EAGLE. Simulation shown in this thesis are implemented in the program OrCAD PSPice. Objective is to ervive all the functional blocks as a whole and the subsequent measurement of basic parameters, which are pro- cessed graphically. All parameters are measured at the end compared with the expected parameters and the simulations generated in the ideological content. Finally, the work is to evaluate all of the results obtained and compared with the primary objective of this work.

Design of switching laboratory source
Moravec, Pavel ; Klein, Richard (referee) ; Steinbauer, Miloslav (advisor)
In present days there is no scientific laboratory without quality, adjustable and powerful source of voltage and current. Therefore this thesis is focused on creating such power source, which can provide voltage and current high enough for most of experiments or for development electrical devices or parts, which are not connected to power grid. This power source is able to provide symmetric voltage 30 V and current 6 A high in each branch. It is possible to control this power source remotely thanks for USB interface, which is standard equipment of majority of modern devices in these days. LCD display is part of this source, which shows the user set and real parameters at the output as well.
