Electric drive of the wheelbarrow
Lažek, Tomáš ; Procházka, Petr (referee) ; Pazdera, Ivo (advisor)
This bachelor’s thesis deals with proposal of an electrical low-cost drive for the wheelbarrow. The first part of thesis is devoted to overview of operational characteristics of available electric motors, batteries and gears suitable for the construction of an electric drive. In the next part the thesis deals with the design and implementation of a pulse converter for a specific DC motor. The converter will be controlled by the integrated circuit UC3638.

Design of switching-mode regulated power supply
Zelinková, Lenka ; Kováč,, Michal (referee) ; Brančík, Lubomír (advisor)
The thesis addresses the conceptual design and implementation of the switched-mode power supply having the adjustable dc voltage output up to 25V and current output up to 15A. The half-bridge topology is used for this supply. Design features and quantities are simulated in PSpice and Micro-Cap simulation tools. The thesis covers the simulation results, assembly data and the results measured on the implemented functional sample.

Small DC/DC step-up converter
Koncer, Adam ; Feiler, Zdeněk (referee) ; Červinka, Dalibor (advisor)
This bachelor´s thesis deals with the proposal and realisation of the small DC/DC pulse converter. First of all I going to focus on teoretical facts and explanation of function and deviding of DC/DC pulse converters. As a next step I going to designing of DC/DC step - up pulse converter 6/12V, 50W, selecting efficient component and construction of whole converter. Trial test will be performed on the final product.
