Design of switching stereo audio power amplifier
Christen, Jiří ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
This work deals with complete design of switch - mode audio power amplifier. The first part of the work describes basic principles of power amplifier operating in switch mode and differences between classes. Specific parts of the amplifier are analysed according to function and construction. The second part includes particular design and construction of the class D switching amplifier with a minimal output power 2x80W. The power stage is realized by an integrated circuit TAS5630 from Texas Instruments. Basic states of the power stage are signalized by LED diodes. The design includes correction preamplifier for adjusting volume and frequency response. The appliance is supplied from switch - mode power supply. Basic parametres were measured for individual parts.

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.

Controllable decorative lighting system
Pelán, Pavel ; Matěj, Zdeněk (referee) ; Fedra, Zbyněk (advisor)
ecorative lighting strips could be used to the backlight of furniture, to creating a modern interior design. From an architectural point of view, this design is very difficult and requires a strong sense of aesthetics. More easier is to use the LED strips to the advertising trailers or to backlighting car parts. RGB strip will be powered by switching power supply with galvanic isolation. Colour will be changed by the combination of basic colours RGB, by using 3-channel PWM of Atmel microcontroller, controlled via a wireless module, providing two-way communication..

Switching Power Supplies Based on TOP Switch
Wolfshörndl, Robert ; Dřínovský, Jiří (referee) ; Šebesta, Jiří (advisor)
This bachelor’s thesis deals with the use of the TOPSwitch switching devices for DC / DC converters powered from the supply voltage 230 VAC. The main part of the Semestral thesis is a program (MS Excel sheet), which conducts all the calculations necessary for the selection of the optimum TOPSwitch device, transformer, feedback circuit and external components required for the design of the switching power supply. The first chapter of the Semestral thesis contains the general description and categorization of the switching power supplies utilizing the transformer. The following three chapters concern themselves with the basic parameters of each of the TOPSwitch device production series. Next chapter describes the step-by-step technique of the switching power supply design using the Excel program. The last three chapters deal with the design of the specific switching power supply, including the design of a transformer and measure the basic parameters designed resources.

Industrial power supply with output control
Čunderlík, Dávid ; Herencsár, Norbert (referee) ; Krajsa, Ondřej (advisor)
This bachelor’s thesis covers basic theory about power supplies, it’s design and usage. Theory provide detailed information about each functional part in PSU. The main object are switch-mode power supplies and converters, their function and design. Industrial power supply is designed with functions of controling the outputs. This power supply is designed to be mounted on DIN rail. Designed power supply have 6 independent regulated outputs with total power of 120W. Theory about components for controling and comunicating are discused on theoretical basis. Practical part of thesis is assembly of a whole power supply, 3D model and it’s technical documnetation.
