Switch mode supplies
Kadlecová, Lucie ; Červinka, Dalibor (referee) ; Patočka, Miroslav (advisor)
In this bachelor‘s thesis is described the design and construction of switch-mode power supply with a pulse transformer. It is mainly focused on projecting and putting into practice of the basic functional elements - LC filter, pulse transformer, transistor converter, transistor drivers, rectifiers and control circutory, including experimental testing of the final product.

I/O Card Controlled by SMS
Bachtík, Martin ; Pavelka, Ondřej (referee) ; Orság, Filip (advisor)
The aim of this bachelor's thesis is design and implementation of a universal device with input-output character. The device detects incitations on few inputs and sets few outputs. The user controls the device via SMS or short multiple dialling. The device interacts with the user via LED diodes, SMS or hort multiple dialing.

High efficiency laboratory power supply
Tejmlová, Lenka ; Vochyán, Josef (referee) ; Petržela, Jiří (advisor)
The project shows the problems of power supply in electrical engineering. It describes the general parameters of these types of supplies and presents their characteristics. Based on these findings, it is also focused on the selection of specific elements of the laboratory supply, to reach the given parameters. It contains the recalculations of the parameters of other additional components. The overall scheme of the supply is divided into several blocks, thematically corresponded to subchapters. According to the accomplished concept the laboratory supply is realized and its parameters had been tested. Projects results are assessed at the end.

Digitally controlled laboratory power supply
Spáčil, Petr ; Drexler, Petr (referee) ; Szabó, Zoltán (advisor)
This bachelor thesis deals with the divison and research of DC voltage sources. It also describes how linear and switch mode power supply works. The 8-bit ATmega16 microcontroller from the ATMEL family of AVR microcontrollers is further described. Part of this bachelor thesis is the desing of the laboratory power supply source 30V / 3A, which is in the topology of switched pre-regulation. The ATmega 16 microcontroller provides measurement and displaying values on the display.

Switched battery charger
Špatenka, Vojtěch ; Kubíček, Michal (referee) ; Kovář, Jan (advisor)
My bachelor thesis deals proposal of switch battery charger and with an issue of charging lead-acid accumulators. It describes their attributes and charging characteristics. Futhermore, it describes a concept and a construction of a switch-mode power supply for charging of these accumulators. The design of a switch-mode power supply according to the programme PI EXPERT 7, the design of an impulsive compensator, the choise of a framework and a centre core, a full-scale scheme of a connection, the design of a PCB, a materials scheduling and their layout on the plate. A concept of controls of the switch-mode power supply using single-chip microprocessor C8051F320 HQ manufactured by Silicon Laboratories. A scheme of integration, a concept of the printed circuit board and a specification of components. At the end of the bachelor thesis was made a suitable chassis from the polycarbonate material. The results and the evaluation of the basic parameters of the of the switch-mode power supply are included.

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.
