Off-grid system and container housing
Filka, Tomáš ; Kracík, Petr (referee) ; Poláčik, Ján (advisor)
This thesis sums up current possibilities of using renewable energy sources and addi-tional technologies which can be suitable for off-grid systems. Specifically, it describes the possibility of their application to the increasingly common container structures. The first part of this work contains information about history and present trends in the area of renewable energy sources and container housing. The second part shows a concept of such house, completely disconnected from the public grid. The results of this study allow basic insight into the problem and illustrate the practical application of acquired knowledge.

Identification and detection of defects on the PV system - operational measurement
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This work deals with the problem of identifying and detecting faults in photovoltaic systems. This thesis includes theoretical knowledge related to photovoltaic panels, the definition of measured parameters of the PV system and five ways how to identify faults in PV systems. The last part of this bachelor thesis deals with the author's contribution, which is to introduce a system for continuous monitoring data. System for continuous monitoring of data consists of measuring the power output of a photovoltaic panel and measurement using optical diagnostics using thermal camera. In conclusion are summarized individual knowledge, evaluation and recommendation of appropriate measurement methods for the detection of faults in PV systems.

Concept of Charging Stations with off-grid Operation for Electric Bicycles
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This thesis deals with charging stations for electric bicycles powered by renewable energy. The aim of this work is to make a proposal for the hybrid charging stations for electric bicycles, which will work independently and, if necessary, will be backed up by a network. In this thesis is entered theoretical information on the issue of electric bicycles, the batteries, charging stations, the connectors of chargers, and photovoltaic systems. The practical part of this thesis is the basic design of the charging station and its design of the mathematical model of the individual parts in Simulink program, which are linked to the actual design of the charging station. In conclusion, this thesis deals with energy and economic analysis of the proposed system, therein included various methods of assessing investment recommendations of appropriate processing methods and overall assessment of the subject.

Motor inverter for Formula Student
Macko, Maroš ; Tomíček, Pavel (referee) ; Šteffan, Pavel (advisor)
This thesis is focused on a power inverter for traction motors for a Formula Student car. Part of the work involves the design and implementation of this system. The main high-voltage power board design and the selection of suitable components are described. Furthermore, a secondary board is designed, which is used for communication and diagnostic measurements. All systems must comply with the rules of the Formula Student competition.
