Processor controlled backup power supply
Hořák, Jan ; Štraus, Pavel (referee) ; Kubíček, Michal (advisor)
This thesis describes the design of a processor controlled small battery backup power supply. The aim is to design a device which can recharge many kinds of mobile devices with a battery capacity up to 2Ah. The main control element is a microprocessor that records operating data of the power supply and stores in onto an SD card. Portability and durability were taken into account during the design. The result is completely designed and build a backup power supply, including program for its microcontroller.

Szabó, Michal ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This document describes a device capable to determine geographical position thanks to its GNSS module and measure the change of movement with the help of an accelerometer and gyroscope. Outputs of these integrated circuits are combined, data are processed and fused thanks to a numerical integration and mathematical filters. Results are stored on a memory card. The whole development is described from a concept, through the making of the device and software algorithms to the testing of its functions.
Design of a photovoltaic power system with battery storage for household purposes in area of Brno-mesto
Vrana, Martin ; Vanýsek, Petr (referee) ; Vaněk, Jiří (advisor)
Táto bakalárska práca sa zameriava na rešerš technológií obsiahnutých v návrhu fotovoltického systému, ako sú solárne panely, nabíjateľné akumulátory, a systémy na premenu elektrickej energie. Následne sú tieto informácie využité na návrh hybridného a sieťového fotovoltického systému pre rodinný dom nachádzajúci sa v lokalite Brno-Mesto. Plán realizácie je nájsť cenovo výhodné riešenie s rozumným časom návratnosti, ktoré prevažne pokryje energetický odber domácnosti. Takisto sú náklady každého zo systémov znížene o dostupné štátne dotácie podľa parametrov každej inštalácie. Sieťový systém je lacnejší ako hybridný systém, pretože systém neobsahuje drahé batérie. Preto má nižšiu dobu návratnosti šiestich rokov, v porovnaní so siedmimi rokmi v prípade hybridného systému. Hybridný systém je výhodný, pretože umožňuje lokálne ukladanie energie a poskytuje záložné napájanie v prípade výpadku prúdu. Dodávateľ elektriny umožňuje uložiť prebytočnú energiu vyrobenú systémami do virtuálnej batérie, z ktorej je možné počas roka čerpať v čase nedostatočnej výroby energie. V kombinácii so súčasnými vysokými cenami energie majú oba systémy relatívne krátke obdobie finančného bodu zvratu v porovnaní so systémami v minulosti. Finálny výber typu inštalovaného systému je na klientovi.

Cílem této semestrální práce je vypracovat rešerši na téma různých metod uskladnění elektrické energie. V práci jsem zkombinoval mnoho datových zdrojů a pro každou technologii jsem vytvořil stručný popis historie, současných problémů a možností do budoucna. Má práce čtenáři poskytne přehled faktografických informací na téma akumulátorů, palivových článků, superkondenzátorů a průtokových baterií. Příslušné technologie jsou uspořádány jako strukturovaný, kategorizovaný seznam.
Design of the electric locomotive drive
Dočekal, Martin ; Klíma, Bohumil (referee) ; Patočka, Miroslav (advisor)
The focus of the work is the calculation and design of battery-powered drive of locomotive, operating in the sub-siding mode, ie when the locomotive is moving on the track section without the overhead line. The proposed battery groups to ensure the drive train will be installed directly into the locomotive engine room. In the theoretical part of the work there has been done the analysis of the electrical locomotives and electrical unit, which nowadays are used in the Czech Republic in driving of voltage controller with the integrated circuit. Then, in the chapter there is a brief description modern locomotives frequency convertor’s and rectifier’s function. The practical part of the work contains the necessary force and energy calculation for train moving on the determined rails. On the base of the received data, the design of battery groups has been done. These battery groups will work as an independent traction which insures the moving of the train on the determined rails. In the work the design, which consists of STEP-UP and STEP-DOWN convertors, has also been done. The power model and model management were created in Matlab Simulink programme. Data and graphs exported from the Matlab Simulink programm are determined for verifying convertor’s function, which can be found in a separate chapter. In addition to the proposal of the battery drive is at work also has been calculated loss of traction rectifier during normal operation of the locomotive, ie outside siding mode. For this calculation, in the conclusion is listed the theory of calculation of the losses incipient in the transistor and freewheeling diode of rectifier. According to the theory own calculation is performed. Subsequently the liquid cooler calculation of the rectifier is calculated.
