Narrowband PLC communication based on G3-PLC, PRIME and IEEE-1901.2 standards
Skrášek, Tomáš ; Šilhavý, Pavel (referee) ; Mlýnek, Petr (advisor)
Diploma thesis is about narrowband PLC communication standards. The theoretical part describes details of all available OFDM standards including G3-PLC, PRIME, IEEE-1901.2 and G.hnem. The practical part deals with PRIME and G3-PLC standards. In this part is also compared OFDM technology with system of single carrier frequency in environment with real interferences. The last part describes developement of two firmwares for PLC modems Texas Instruments TMDSPLCKIT-V3, which allow UART communication and remote data collection. The thesis also includes Windows application developed to display and save collected data.
Concept of three-phase active rectifier
Bareš, Jiří ; Pazdera, Ivo (referee) ; Huták, Petr (advisor)
This work deals with three-phase active rectifier control. In first, theoretical part it describes several control strategies with focus on voltage oriented control. For this type of control a design is worked out, and created model and its simulation is described. Second, practical part deals with realisation on microcontroller TMS320F28335, which is main processing unit of device lent by company Elcom. Therefore in this part abilities and settings of the controller along with developped control algorithm are described. Reached results of measurement are then presented and in the conclusion they are evaluated.
Control of Three-phase Sinusoidal Power Source
Žůrek, Tomáš ; Patočka, Miroslav (referee) ; Klíma, Bohumil (advisor)
This thesis deals with control of three phase inverter as three phase sinusoidal voltage source for UPS application. Thesis is split to two parts, teoretical and practical. Teoretical part deals with three phase inverter topology analysis according requirement of neutral line wire and possibilities of generating sinusoidal PWM in depend of topology. There are also analysed properties of contorled system and designed 3 regulation methods with simulations. Second part of thesis deals with realisation of sinusoidal power source with inverter borrowed by Elcom company. To inverter control is used digital signal controler TMS320F28335 with implemented control algorithms. There are also presented the measurement results of the prototype of power source. In conclusion, simulation results are compared with measurements and achieved results are summarized.
Irrigation automatic machine
Krištof, Martin ; Musil, Vladislav (referee) ; Šteffan, Pavel (advisor)
The aim of the bachelor's thesis is to design an irrigation automat. The bachelor's thesis describes a concept realized with the microcontroller TM4C1294. In the theoretical part of the bachelor's thesis, the fundamental terms are explained and irrigation automats are described. The practical part includes the design of hardware and software. The proposed solution allows irrigation using different methods and connect moisture soil sensor, air humidity and temperature sensor and water flow sensor.

Embedded solution design suitable for automatic attendance system
Filakovský, Petr ; Mašek, Petr (referee) ; Věchet, Stanislav (advisor)
The thesis proposes a firmware for the microcontroller, which is connected to a host attendance system using TCP / IP protocol. Created firmware processes the data from RFID and other peripherals, such as LCD graphic touch display and SD card. Firmware is created in the programming language C / C ++ in development environment TI Code Composer Studio.
