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.

Electric motorbike traction drive
Bartoš, Jiří ; Vorel, Pavel (referee) ; Martiš, Jan (advisor)
This work deals with complete designing of electric drive for lightweight motorcycle. There are mentioned options of electric drive and types of batteries. One solution for Jawa 50/555 motorcycle frame is picked. In this work are measured losses of traction motor and cooling system is modified. There are some necessary calculations of drive. In next part 10S6P Li-ion battery with balancer and undercharge controller is realized. In this thesis design of step – down converter with current control is described, cooling and PCB is proposed. Complete converter with cover is made.

Design of a convertor for a BLDC motor
Stejskal, Martin ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
This master thesis deals with the design and realization of a drive for a 500 W BLDC motor powered with a battery power supply. It also deals with the possibilities of realization of drives and other possibilities to control these motors. Describes the implementation of the inverter using Atmel's AVR microcontroller. The thesis also deals with the design of an auxiliary switching inverter. Communication with UART and CAN interface is also implemented.

Low frequency active artificial load
Lízner, Václav ; Papica, Petr (referee) ; Kubíček, Michal (advisor)
This diploma thesis is focused on synthetic loads, especially electronically controlled loads. The thesis analyse principles of mechanically and electronically controlled loads and theirs operation modes. The paper also carried out a search of AC loads available on the market. The parameters of the AC load were based on the requirements provided by client. The functionality of the designed load is verified by simulation. The thesis continues with realization of the designed schematics and bringing the load to function. At the last section of the thesis are detail parameters of the designed load verified by measurement.

Controllable power supply for LED lighting
Morávek, Petr ; Pavlík, Michal (referee) ; Boušek, Jaroslav (advisor)
This thesis deals with the description of artificial light sources, that use light-emitting diodes for their operation. Further down, the parameters of LEDs and their emissions are detailed. The work follows with the characterization of principles of LED power regulation. In the practical section, an example of one of the possible LED light source topologies, is designed. The offered solution includes the options to manually and automatically regulate the chromaticity of emitted light. Functionality of the solution was verified experimentally.
