Design and construction of double laboratory power supply
Klein, Miroslav ; Šebesta, Jiří (referee) ; Brančík, Lubomír (advisor)
This semester thesis deals with design of double laboratory DC power supply with adjustable voltage and current limitation. Power supply can work in two states. First state allows regulation of output voltage from 0V to 40V and current limitation from 0A to 3A. In second state the range of output voltage is from 0V to 18V and output current can be set from 0A to 6A. Both supplies are galvanically separated and can work independently, or can be combined. Whole power supply is digitally controlled by microcontroller.

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 linear power supply
Mikulka, Martin ; Šteffan, Pavel (referee) ; Háze, Jiří (advisor)
This bachelor thesis is focused on the design and realization of laboratory power supply with digital control. The power supply contains two separate galvanically isolated channels with output parameters in ranges of 0 - 24 V and 0 - 5 A. Output parameters are controllable independently via front panel or remote control. This power supply allows user to connect other channels meeting the condition of galvanic isolation and communication via the I2C interface. The content of this work is a theoretical analysis of the design of linear regulators, design with practical implementation and subsequent measurement.

Adjustable Laboratory Power Supply
Skryja, Petr ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
The aim of this work is to enlighten the reader with topic of linear power sources and guide him through designing his own adjustable laboratory power supply. Design of adjustable laboratory power supply uses the stabilizer L200 with voltage regulation and current limitation. Device is expanded with digital part (using ATmega8 MCU) to enable peripherals control and measured values processing. The laboratory power supply will be constructed and its parameters will be measured.

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.
