Laboratory Switching Power Supply
Slezák, Jakub ; Petržela, Jiří (referee) ; Šebesta, Jiří (advisor)
This bachelor’s thesis is concerned with design switching power supply based on forward converter with output voltage regulated in the range of 3 to 30V and load current to 1 A. First of all, it discusses the theoretical solution of basic types of converters and switching power supply problems. Followed by a proposal of various parts source, which was first established in the test version on the test board. Then was proposed printed circuit board and complete mechanical solutions. Source is also equipped with digital modules for measuring voltage and current, and is protected against overload.

Design of supply source with several outputs
Lačný, Radek ; Lattenberg, Ivo (referee) ; Novotný, Vít (advisor)
The main objective of this work is a design of supply power source with several outputs for a telephone subscriber module. This module consists of two parts. First one is a control block containing a processor and auxiliary circuits, which requires voltage +3.3 V and +5 V. The second part is a board with cards, which provides dual telephone line feeding each and the board requires voltage in the -24 and -75 V. Bachelor's thesis contains a brief description of the basic types of convertors used in switched power sources, then the design of required power supply for the subscriber module together with the draft printed circuits and also the alternative power sources based on commercial products available on the Czech market. The resulting electrical scheme of power supply, including the printed circuits board schemes are presented in the Annex of the thesis.

Home security system - base board power supply
Peša, Ondřej ; Šťastný, Ladislav (referee) ; Fiedler, Petr (advisor)
This bachelor's thesis deals requirements for alarm system power supplies and includes familiarization with the issue of charging lead-acid batteries and an explanation of the basic principle activity step-down switched – mode power supply. The main goal of this project was to design and implement a functional model of the power supply with lead-acid battery. The power supply includes a battery charger circuit, which when accompanied by a power failure back-up and circuit protects the lead-acid battery against deep discharge UPS is in normal operation continuously charged. The proposal was developed in the program for PCB design Eagle 6.1.0. Functional model was implemented in a single PCB, which together with the battery and transformer were placed in the box.

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).

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.
