A traction drive for an electric bike with motor "Heinzmann"
Němec, Petr ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This work deals with a proposal and construction of a DC/DC converter for a control of a DC motor Heinzmann. The DC/DC converter will be used in an electric drive for a bicycle. The proposal of the DC/DC converter is designed for such engine power to avoid fully any human force to drive - pedaling. The work includes informations about the used motor, progress of proposal and dimensioning of the converter - power circuit and control electronics.

Wireless Nurse Care Calling
Bubník, Karel ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
This work describes the design, construction a performance of such a complete wireless pager suitable for health care centers, rest homes, home application, for example for calling an attendant. This appliance is designed to be easy to attendance. A wireless transceiver is simplified and is attended only by one button. A wireless receiver also doesn't require a complicated manipulation. The aim is to create pager, which will be an useful assistant thanks to its price and simple construction.

Design inverter using semiconductor on based SiC
Kharchenko, Vadym ; Procházka, Petr (referee) ; Kuzdas, Jan (advisor)
This work builds on a semester project 2. from the winter semester of this academic year. The aim of this thesis is the design of converter using semiconductor components based on SiC technology. This converter is used in the construction of quick charger for electric vehicles. The design of this converter must be based on the requirements for compliance voltage safety. It describes the design of power components used in the construction of this facility, the determination of their losses and determines the overall efficiency of the converter. There is also proposed mathematical model of high-frequency transformer and made his simulation in Matlab-Simulink.

Bycicle with Combustion Engine and Electrical Transfer of Power
Mazálek, Tomáš ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
The objective of this semester thesis is design of the control algorithm, needed control and power circuits and PCB design for the unfinished bicycle concept with a combustion engine and electric power transmission. The control algorithm had to be designed to make efficient use of the combustion engine performance and to minimalize the fuel consumption and noise level of the device. All circuits are fully implemented by analog components for which were designed printed circuit boards using program Eagle and this boards were revived and debugged.

DC-DC converter for matrix controller system for LED
Gociek, Krzysztof ; Janík, Lukáš (referee) ; Hudcová, Lucie (advisor)
This diploma thesis deals with design and subsequent realization of DC / DC converter for supply of matrix LED fields for the automotive industry. Such a converter must be able to supply a current of several Amperes and a voltage of the order of tens of Volts. Matrix headlights are currently being developed by a number of automotive companies. These headlamps allow independently to control the intensity of light incident on different objects or people who are in front of a car. In addition to the front headlamps the matrix LED lights are also used in the rear and signaling lights. Here it serves mainly to create different animations that have no function except the overall enhancement appearance of the vehicle. All of these lights need power units that will be suitable to regulate current flowing into various combinations of LEDs illuminated.

Low-power electrical sources
Kotásek, Ondřej ; Pazdera, Ivo (referee) ; Procházka, Petr (advisor)
In the theoretical section describes the different types of DC / DC converters, which are among the best known. It's a drive with one storage element, decreasing and increasing non-inverting converter, an inverting converter with a common choke and Čuk’s changer. The second part deals with the actual design and implementation of the two input sources for low power. Here are described two main components designed for each circuit. Furthermore, the work to create schematics and PCB in Eagle. Finally, learn how to solder components on the PCB made.
