Hardware design of diesel injection system control unit
Novák, Matyáš ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
This master’s thesis deals with the basic design of diesel injection control unit hardware. There is a description of the whole blocks of Motorpal Common Rail diesel injection system in the introduction. Next are described requirement of control unit hardware. In the following are descriptions of parts, which was choosed for adjustment. The second part of thesis describes the whole design of control unit wiring diagram. There is described each block in detail in this part. Next part describes component placement on printed circuit board. The conclusion of thesis compare designed version of control unit with elderly versions.

Transient Thermal Response Measurements
Stejskal, Martin ; Čala, Martin (referee) ; Beneš, Petr (advisor)
This Bachelor thesis is interested in measurement of thermal parameters of three-phase power switching module. The module contains IGBT power transistors and power diodes, whose dynamic parameters are measured. Based on these measurements, substitute thermal models are constructed, necessary for heat loss simulations and calculations.

Distance Practical Education of Electric Machines
Šelepa, Jan ; Huzlík, Rostislav (referee) ; Hájek, Vítězslav (advisor)
This work contains scheme of practical point of distance training in the field of electric machines. It consits of three parts nessesary for consistence of entire work. In first part we have a description of data networks used to communication with virtual laboratory. Further there is a list and description of software fit for our study. These are programs capable of controling measurements, e.g. . LabView, Control Web, TestPoint, ScopeWin etc. In second part we have selection of measurment experiment. As experiment i measured the effectivness of three-phase transformer. The values archieved during the experiment where recorded and processed into form of graph and tables. In last part i used processed results to create functional simulation of measurement using MS Excel software. Further i calculated characteristics for equivalent circuit diagram of the transformer, that where equivalent to the real values measured in laboratory.

Class H audio power amplifier design
Spáčil, Tomáš ; Šebesta, Jiří (referee) ; Dušek, Martin (advisor)
This bachelor´s thesis is dealing with a plan of a low frequency ending amplifier of class H that is made of discreet parts. Content of this work is an explanation of basic terms and classes of ending levels low frequency amplifiers. The ending level in class H is written in detail including its possible kinds of solution. The own solution of amplifier in class H is completed by simulation and areal connectors to individual parts. The aim of this work is a prototype of a final look of a device with record about measurement of its basic qualities and their evaluation.

Simulation of circuit-breaker trip unit
Dostál, Lukáš ; Augusta, Zbyněk (referee) ; Valenta, Jiří (advisor)
Securing of electrical devices is important not only to protect against destruction under the effects of electric current, but also for protection of people or animals against electric shock. With increasing of living standards goes hand in hand increasing of the electricity consumption. Therefore In the grid of low voltage, there are increasing short-circuit currents. With improving technology is posed considerable demand on the performance, security and switching capacity of circuit breakers. This thesis is oriented on development of thermal and electromagnetic switch of circuit breaker on which is put a big demand in development of new types of circuit breakers. The thesis is interesting because of comprehensive use of circuits’ breakers since it can be used in AC and DC networks with frequency of 50 Hz and 400 Hz.
