In this work I aimed at designing a universal system for testing either STM32F407/417 by STMicroelectronics and later various sensors and communication buses. The result then is a main board with many specific connectors for individual buses even with connectors making all I/O pins accessible at the same time. Thanks to advanced switching regulators the power supply is capable of accepting a wide range of sources like single Li-Ion cell, pair of alkaline cells, 12V Lead battery, common wall power adapters (both DC and AC up to 15 Vpp ), USB, laboratory power supplies with multiple outputs and finally POE (Power Over Ethernet). Supply voltages are supervised by voltage comparators with an optical signalisation. (It is possible to determine the sick branch without a measuring instrument and blowing components in the most cases.) Another important parameter was a robustness of the supply and communication lines. There is a number of TVSs, chokes, and big and low ESR capacitors A PC software is intended for a basic functionality demonstration only.

The contents of this thesis is design of audio power amplifier in Class D with fully digital control and remote control and is divided into two parts . The first part is devoted to the basic principles and theory of key elements of the entire amplifier. The second part consists of a complete description of the design and construction of a power amplifier, digital control with remote control, a spectrum analyzer, equalizer, preamp VU meters and complete power supply. Each proposal contains a detailed analysis of the solutions supported by simulations and software. For individual parts have been completely measured p arameters.

The subject of master’s thesis is introduction with the principles of measuring voltage, current and electrical power in DC and AC systems. Is designed measurement system for normal household. Measurement system includes pricing and client billing. User interface Ethernet-based is implemented.

Master‘s thesis is focused on problematic about state of RC plane model during the flight. Device is able to measure overload, height, position, pressure and velocity of the flight and store this measurement data to memory medium. The main aim of the master‘s thesis was to design a functional board, firmware for device and design simple program for evaluating of measured data. Involvement consists of five basic parts. First part is microcontroller, which processes measurement data and communicate with others parts. Next is accelerometer. Accelerometer is used for scanning overload of the plane. Barometer is used for measurement of height and pressure. For measuring position and velocity is used GPS module. Last part is memory medium. MicroSD is used as memory medium for storing measurement data. Evaluation of measured data is realized as simple program with base graphical user interface. Program was created in Matlab.

A conceptual design and realization of a motor bike using combustion engine and electrical power transfer is the objective of this master´s thesis. Control strategy that allows combustion engine to reach maximal efficiency cooperating with wide range speed and torque operating area electromotor was created. All function blocks were realized. Also hardware of all needed parts was developed. The last part was a design and debugging of control software. Finally the functionality was documented by test drives and measurements.

This master's thesis is interested in concept of frequency converter for induction machine to power 2 kW. Control of this converter is wirelessly or via PC. The solution is based on execution with integrated circuits and microprocesors to control them.

The master’s thesis is focused on the UHF RFID reader EXIN-1 signal processing. The first part describes the concept of the EXIN-1 front end, its basic testing and possible communication interfaces for reader control and for receiving and transmitting baseband signals. The second part of this work is aimed to a simple description of EPCglobal Class-1 Generation-2 UHF RFID Protocol, especially to used modulations and codings. In the last part, a block connection between the front end and an ARM Cortex-M4 microcontroller discovery board is designed. The microcontroller is used for generating of all required signals and also for receiving incoming signals and processing them for identification numbers of RFID cards (tags), which are in the reading range of the reader. A decoding algorithm is designed in MATLAB software and implemented to the selected microcontroller. Obtained identification data are displayed on an LCD display and also sent to a PC through a serial communication.

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.

This thesis is focused on a creating supporting drivers and algorithms for electrical motor control using CPU TriCore TC275 CA. The first part is devoted to processor description and selected peripherals, which are A/D converter, a timer for creating the PWM signals and the second timer for processing singnals from encoder. All drivers are tested on an aplication kit, which is equipped with TC275 CA processor. The second part analyzes the measurement quality of GMR sensor TLE5009. Special testbench was prepared for sin cos data capturing and for their comparison with precise encoder position measurement. It was composed from DC motor having both sensor types on commons shaft. Data are acquired using LabView. Subsequently, it analyzes the sensor data, their compensation and subsequent comparison with measured data from the encoder.

This thesis deals with the measurement of physical quantities in building using decentralized system for data collecting. The system consists of Raspberry Pi as a master device of the system. There are three branches connected to this master device. Each branch consists of up to 32 modules for data-concentration from sensors of physical quantities. The Raspberry Pi has implemented web interface for displaying measured values and system administration.
