Analyzing measured data in MATLAB
Loup, Martin ; Pazdera, Ivo (referee) ; Huták, Petr (advisor)
Analysis of the measured data is an integral part of each measurement. The focus of this bachelor's thesis was to facilitate the processing of results of measurements. Therefore an application was created that can retrieve the data from the file and further analyze them. The application is thus able to create a variety of graphical dependencies, to calculate a new variable from the loaded values, save all variables, to determine the basic parameters of the signal or convert a signal to another signal type.
Electronic ballast for sodium lamp
Eliáš, Jaroslav ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
The aim is to get acquainted with the way the management and regulation of sodium lamps. This knowledge is then applied to design your own gear. The introductory section describes the basic characteristics of discharge light sources. Their behavior was verified by measuring and findings were used to create diagrams, mainly the control circuit. Theoretical design is developed by individual functional parts of the inverter.
System of DC/DC converters for solar cells of a fotovoltaic power plant
Benda, Dušan ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This master thesis describes the design of a DC/DC converter for one photovoltaic panel with a 250 W peak power. The master thesis is divided into parts dealing with detailed design of power electronics, analog circuit design, description of control MPPT algorithms and software for control circuit. The chapter with the mathematical modeling of the converter created in the Matlab Simulink was added beyond the assignment.
Fast data logger with galvanically separated measuring channels
Doležel, Jiří ; Knobloch, Jan (referee) ; Huták, Petr (advisor)
Master‘s thesis deals with analysis solutions and construction of the devices for data collection. At the beginning, they describe the basic types of devices for data collection. In other parts of the work is compared few commercial devices for data collection, under which the requirements will be selected on the proposed device for data collection. In other chapters of the work devoted to the design of schemes and selecting components for their manufacture. The last chapters are devoted to describing the design of device for data collection.
Resistive Heating System for Work Shoes
Pár, Lukáš ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This bachelor thesis deals with the design of a device for the resistive heating of work-shoes, the circuits of a power converter for a heater and the battery-pack. Two variants of the heater are designed in the first part of thesis. Thesis continues with design of DC/DC converters for both types of the heater. Next part of the thesis deals with a design of the battery-pack with simple BMS circuits. The design of the control circuit for selected DC/DC converter follows. Next part of thesis deals with the construction of the device. Last part is dedicated to measurements and verification.
Bycicle with Combustion Engine and Electrical Transfer of Power
Mazálek, Tomáš ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
The objective of this semester thesis is design of the control algorithm, needed control and power circuits and PCB design for the unfinished bicycle concept with a combustion engine and electric power transmission. The control algorithm had to be designed to make efficient use of the combustion engine performance and to minimalize the fuel consumption and noise level of the device. All circuits are fully implemented by analog components for which were designed printed circuit boards using program Eagle and this boards were revived and debugged.
Topology Recognition from Crossroad Plan
Huták, Petr ; Bartík, Vladimír (referee) ; Kreslíková, Jitka (advisor)
This master‘s thesis describes research, design and development of system for topology recognition from crossroad plan. It explains the methods used for image processing, image segmentation, object recognition. It describes approaches in processing of maps represented by raster images and target software, in which the final product of practical part of project will be integrated. Thesis is focused mainly on comparison of different approaches in feature extraction from raster maps and determination their semantic meaning. Practical part of project is implemented in C# language with OpenCV library.
Electronic load
Doležel, Jiří ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
Bachelor’s thesis deals with the analysis solutions and construction of the DC electronic loads. At the beginning, they describe the basic principles of electronic loads. In other parts of the work is compared commercial electronic loads, under which the requirements will be selected on the proposed electronic load. In other chapters of the work devoted to the design of schemes and selecting components for their manufacture, including dimensioning of cooling power parts. The last chapters are devoted to describing the design and measurement of electronic load.
Simulink transformer models based on equivalent circuits
Petrič, Peter ; Huták, Petr (referee) ; Pazdera, Ivo (advisor)
The aim of the bachelor‘s thesis is to project and then realize models of transformer in Matlab/Simulink program. These proposed procedures show the relation between original transformer and its spare connections. The first part of bachelor‘s thesis is oriented to theory of transformers which defines basic parametres and relations between them in transformer. Later in this part we try to describe cross-over from basic transformer model to the spare connection which is needed in realization of model in Simulink. The second part of bachelor‘;s thesis is oriented to theoretical description of vector transformation. It describes some basic relations of general transformation, currents transformation and voltage in certain connections. The third part of bachelor‘s thesis shows some practical realization of spare connection models of basic transformer in Simulink program. In this part we modeled some current transformer models and voltage for single-phase and three-phase system. As to compare we have created process of currents and voltages in transformer as well as power and load of each model.
Miniature charger for a battery pack Li-ion 14,4V/2Ah
Bartoš, Miroslav ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This bachelor‘s thesis describes the design chargers for lithium-ion batteries. The proposal includes the selection of suitable converter topologies, design power, control and excitation components and a design of high frequency transformer. In the next part the thesis deals with the BMS, which stands for battery management system. The last part deals with the production of the proposed switching source and BMS. The project documentation for the production of a charger is also provided.
