Modular Power Supply for Formula Student
Ščípa, Samuel ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This bachelor thesis is focused on the theoretical analysis and design of switching power supply with galvanic isolation. The implementation of the design is in the form of the power and control part of the modular power supply. The device parameters are suited for the needs and requirements of the development department of the electric student formula. Design configuration achieves a maximum output voltage of 1000 V and a current of 100 mA, which are user-adjustable.

Data storage system for area of civil aviation
Kotulič, Dominik ; Novák, Lukáš (referee) ; Šteffan, Pavel (advisor)
In the thesis the design of the Data Storage System (DSS) is proposed with the respect to the V-Model methodology. The design is based on users requirements, from which the system requirements are created and the technical specification of the DSS is developed. In the technical specifications the functionality of the DMM and HMI DSS subsystems are described and sub-system requirements are assigned to them, then they are subdivided and assigned to individual DMM (Data memory module) and HMI hardware items. Moreover, requirements are analyzed on hardware items, specific electronic components, are selected and implemented into the block design of the DMM hardware. Based on the block design of hardware, the hardware of the DMM subsystem is designed, selectively simulated and implemented along with the printed circuit board. On the implemented hardware of the DMM subsystems measurements are performed in order to verify the basic functionality of the hardware and the calculated, assimilated and measured values are compared as well. At the end of the thesis there is a short description of the implementation of the software design and its use for basic initialization of the selected processor, together with the verification of its basic function - measuring the frequency of the internal clock sources and the clock domains. The work is completed by sending a message of defined parameters to the selected communication line and sapling it by an oscilloscope, so that the basic function of the DMM subsystem is verified.

High-Voltage Structures for Galvanic Isolation in Integrated Circuits
Ptáček, Karel ; Husák, Miroslav (referee) ; Zemánek, Miroslav (referee) ; Boušek, Jaroslav (advisor)
Tato dizertační práce představuje novou techniku laterární rezonanční vazby, která je využita v návrhu galvanicky izolovaného posouvače úrovně, který je následně implementován v 800 V půlmůstkovém kontroléru pro průmyslové aplikace. Ve srovnání s tradičními galvanickými izolátory jsou výrobní náklady tohoto řešení nižší. Pro aplikace vyžadující vyšší úroveň galvanické izolace je popsán následný vývoj galvanicky izolovaného posouvače úrovně, který využívá pouze jeden galvanicky oddělený posouvač úrovní pro komunikaci v obou směrech, což výrazně snižuje plochu struktury izolátoru. Jako součást následného návrhu je představen galvanický izolátor který je schopen přenášet analogovou hodnotu napětí. Analogový izolátor byl testován v reálné aplikaci síťového spínaného zdroje jako náhrada standardního optočlenu. Tato konstrukce umožňuje integraci primárních a sekundárních obvodů v jednom pouzdře, což umožní snížit složitost a cenu spínaného zdroje.

Matlab Models of DC/DC Converters
Macík, Tomáš ; Cipín, Radoslav (referee) ; Pazdera, Ivo (advisor)
The Bachelor’s thesis is focused on modeling of DC/DC converters without a transformer using Matlab Simulink software. The first part is dedicated to general explanation of function of selected switch mode power supplies. The second part contains the deduction of equations for every selected switch mode power supply and design of circuit components based on required converter parameters. The models of converters have been created in Matlab Simulink using deduced equations. The models of STEP UP and STEP DOWN converters have been created also using Simscape Power Systems Toolbox and the control of current and voltage has been designed for them.
