Wireless charging station
Navara, Albert ; Dvorský, Adam (referee) ; Šteffan, Pavel (advisor)
The topic of this thesis is the design and construction of a wireless charging station compatible with the Qi standard with the possibility of delivering higher power. A wireless receiver is also designed and constructed to evaluate the capabilities of the wireless charger. Before the design itself, the theory of transmission and procedures for selecting topologies and components are discussed in the thesis. In the design of the transmitter and the receiver, microcontrollers are used, which take care of communication with each other and set the required parameters. The assembled transmitter is tested with a receiver in the form of an LC circuit, with a purchased receiver, and with the designed receiver within various distances and deviations of the transmitter and the receiver. The final product is fitted into a plastic box printed on a 3D printer.

ArtNET and DMX converter
Strouhal, David ; Schimmel, Jiří (referee) ; Krajsa, Ondřej (advisor)
Goals of this thesis is design and realization of Art-net to DMX512 converter. First, a description of the currently used protocols for controlling stage lighting was made. This was followed by a successful proof of concept of the solution and subsequent implementation of the converter including PCB design and programming of the ESP32 processor to convert the protocols.

RGB LED power supply design for aircraft position light system
Potoček, Lukáš ; Dyčka,, Pavel (referee) ; Leuchter, Jan (advisor)
This bachelor’s thesis deals with design of a DC steady-current power supply for position and anti-collision lights of utility aircraft with 28 DC system. Main objective is design of an alternative, which combines 2 items into one, thanks to an option of changing colours of position lights. The work further discusses the requirements in terms of aviation standards and their consideration in the selection of components.

Switch mode supplies
Kadlecová, Lucie ; Červinka, Dalibor (referee) ; Patočka, Miroslav (advisor)
In this bachelor‘s thesis is described the design and construction of switch-mode power supply with a pulse transformer. It is mainly focused on projecting and putting into practice of the basic functional elements - LC filter, pulse transformer, transistor converter, transistor drivers, rectifiers and control circutory, including experimental testing of the final product.

MW Converter for SW Receiver
Lejsková, Alena ; Lukeš, Zbyněk (referee) ; Šebesta, Jiří (advisor)
This thesis concerns about the network synthesis of receivers with the demand for conversion of the input signal and a following implementation of assigned converter. At first it introduces the readers with the basic division of radio waves and with parts, which are important for a high-quality receiver, then it deals with general properties of input networks of receivers, division of parts and kinds of connection, that are used in the communications. The concept of connection is intended to nonspecialists too, that is why it describes step by step each of parts of the network, including the calculation or possible solution and the choice of convenient parts. The aim is also to present the frequency conversion as an important part of signal receiving that we want to use in communication systems.

Modbus TCP interface
Krotký, Pavel ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
Main puropose of this thesis is to design and develop Ethernet to serial interface converter. Ethernet and serial line protocols are briefly described. Appropriate microprocessor and hardware for realisation of each physical layars were choosen. Convertor uses Texas Instrument's TI-RTOS operating system. Convertor's purpose is to pass on communication between physical layers and also fulfill webserver role with configuration possibilities.

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.

Debugging Information in Linker
Nikl, Vojtěch ; Křoustek, Jakub (referee) ; Masařík, Karel (advisor)
This thesis describes the conversion between the CCOFF object file format and the ELF file format. We start with a general object file format and its debbuging information, then we focus closely on the ELF, CCOFF and DWARF debugging information. The functionality of the CCOFF format is encapsulated in the ObjectFile class library. Then follows the description of creating an ELF object file, its filling with the proper data and its conversion back to the CCOFF format.
