Laboraty Pulse Power Supply Using Output Linear Stabilization
Lednický, Marek ; Dušek, Martin (referee) ; Šebesta, Jiří (advisor)
This thesis deals with switched mode power supplies. The theoretic part of the thesis consists of historical development and the elementary schemes of switched mode power supplies. It also includes the comparing with linear regulators. Next, it contains the description of individuals parts switched mode power supplies as a rectifiers, power supplies and stabilizers. There is a proposal and fixing of laboratory pulse power supply using output linear stabilization in the practical part of the paper.

Digitally controlled power supply
Stupka, Dominik ; Drexler, Petr (referee) ; Szabó, Zoltán (advisor)
This document describes design of the laboratory power supply with digital control. Power control consists from a control section which handles communication between the modules and the power section.Into the power section is integrated switching and linear regulator. The designed power supply contains two such modules. To control are used microcontrollers from Atmel. Source parameters are 2 x 30 V / 0 – 3 A. During the construction we have to emphasis on the accuracy of regulation the output values and the modularity of the solution.

Mikroprocesor control for laboratory power source
Hauer, Petr ; Kubásek, Radek (referee) ; Szabó, Zoltán (advisor)
This bachelor thesis aims to design and implementation a laboratory power supply controlled by microprocessor and PC via USB. The theoretical part describes the USB bus and the manner of its implementation to the microprocessor. There are the basic types of switching and linear sources and methods of control by a microprocessor. The practical part deals with the design and implementation of the resource. The results of this work are the themes of control and power part of power supply, printed circuit boards, software for the PC and microprocessor and measurements on the completed source.

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.

USB controlled voltage and current source
Pytela, Ondřej ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
This diploma thesis is focused on complete construction of lab source which is controlled and powered by USB in personal computer. Different types of possible solutions are mentioned and finally one of them has been picked up as a best choice, which is developed in the rest of this thesis. Besides hardware construction there is also shown creation of main program for PIC18F14K50 microcontroller and main application that provides controlling of USB source via personal computer.

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.

Communication module for power supplies controlling
Zachar, Jiří ; Šmíd, Petr (referee) ; Dřínovský, Jiří (advisor)
The aim of this work is to design a communication module for laboratory source Manson. This power supply communicates only through a serial RS-232 link. Modern computers usually use for the connection with other peripherals mainly USB. Designed communication module contains converter between the RS-232 and USB. Power supply is used in the automated measurement setup, which is controlled from the Virtual Engineering Environment from the Agilent Technologies. Direct commands for laboratory source Manson are not compatible with the SCPI (Standard Commands for Programmable Instruments) standard commands. So, the communication module converts commands from the SCPI format to Manson supply instructions. The communication with the Manson supply will be obvious for students by using new communication module.

Design of regulated laboratory source with current measurement
Panáček, Jiří ; Šteffan, Pavel (referee) ; Magát, Martin (advisor)
This bachelor thesis deals with problematic and design of linear laboratory power supply. The first impulse start design of this device was requirement of simple and low cost laboratory power supply with good performance for debugging and measuring electronic circuits. This design keeps modern trend in lab power supplies with driving via microcontroller. This solution makes device easy to control and it is possible change program equipment.
