Power supply with current reversal
Hrdina, Adam ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
This thesis describes the design of regulated power supply that allows the reverse direction of the current. The supply can as well work as an electronic load. The supply has continuous settings of voltage from 0 to 50 V and continuous settings of maximum current from 0 to 5 A. The first part of thesis consist general description of power supply and of electronic load. The second part then includes the main design of overall concept of the supply and design of individual components.

Step down convertor
Koutný, Martin ; Kadlec, Josef (referee) ; Cipín, Radoslav (advisor)
Thesis deals with the evaluation of the solutions and the design of the DC voltage converters. The first describes the different types of converters, which subsequently choose types of resources for the construction. In other chapters of the work devoted to the design of schemes, selected types of sources and selection of circuits and components therefor, for the manufacture, including calculations cooling performance parts. The last chapter is devoted to the description of the structure and measurement of the produced sources. The measurements are primarily deals with the verification of the specified parameters.

Controlled laboratory supply
Štibraný, Miroslav ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
Master’s thesis deals with design of laboratory supply with precise voltage and current measuring. At the beginning it presents properties, advantages and disadvantages of linear and switching supplies, based on these facts it chooses a linear type of regulator. The design continues with detailed description of power and control analog and digital circuits. The thesis includes description of taking control over the supply from the front panel or through computer. The last part is devoted to measurement results and to presentation of some static and dynamic parameters of the designed supply.

Intelligent charger for Pb accumulators
Hadwiger, Tomáš ; Šebesta, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor project deals with lead accumulator charging. The properties of this acumulator charger are described here and the best possible way of charging has been based on these properties. The capacity of the accumulators has also been taken into account. The charger itself is able to distinguish between the twelve-volt and the six-volt accumulator. The charger prevents accumulators from overcharging and does not charge damaged ones.It also contains the protection against reversing polarity. The project contains complete scheme, DSP layout, lists of components and their placement on the DPS. The design of the transformator suitable for the charger is also included.

Hybrid AC/DC,AC/AC substation operation analysis
Lakomý, Marek ; Orságová, Jaroslava (referee) ; Dohnal, Petr (advisor)
The work analyzes the operation of hybrid substations. The first chapter provides an analysis of domestic traction systems and describes in detail specific station. The next chapter follows the first in a way in which obtained parameters are converted to parameters suitable for the simulation program and presents its results. The third chapter discusses the serial communication used in one switchgear and about voltage regulator that controls one high voltage field. The last chapter verifies the simulation results obtained from the second chapter with real measurement and direct comparison is also included.

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.
