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.

Controlled power generator of current impulses
Gabriel, Viktor ; Vrba, Kamil (referee) ; Rampl, Ivan (advisor)
The goal of this thesis is to design and realise microprocessor-controlled generator of current impulses, which are being brought in induction load. Thesis contains description of individual functional generator parts, mainly microprocessor program equipment. The text also aims for inductor design as an induction load and other solutions of power parts with the selection of the most suitable one. The generator of current impulses itself is realised on two-sided printed circuit board.

Traction DC/AC inverter 2,5kW for an induction machine of an electric garden tractor
Krist, Petr ; Patočka, Miroslav (referee) ; Vorel, Pavel (advisor)
This thesis deals with the proposal of power 3-phase DC/AC inverter for an induction machine of small garden tractor. It concerns the choice of a voltage level of DC link, dimensioning of the power circuit, drivers for power transistors, implementation of metering and protection and also processor driving. The whole thing ends at proposal of PCB in the software program called EAGLE and PCB manufacturing. So we also check if the theoretical calculations are correct and if the whole drive works.

Lead-acid battery charger with a pulse converter
Mihályi, Róbert ; Martiš, Jan (referee) ; Vorel, Pavel (advisor)
This master´s thesis discusses on complete designing of a lead-acid accumulator charger. Charger operates with the principle of a two-switch forward converter. It contains the design and manufacturing of all the proposed winding subcomponents, the semiconductor components, the control circuit board and the power circuit board. This thesis includes also the design and description of the individual parts of the power circuit and control circuit. The revival of the charger, including a description of the individual adjustments that were necessary for proper and reliable operation is also in the content. This thesis contains too a series of measurement performed to verify the correct function of the charger.
