Power Converter for the electric arc welding
Jaša, Jakub ; Vorel, Pavel (referee) ; Patočka, Miroslav (advisor)
This thesis deals with the peripheral design, construction design and implementation welder DC arc. The concept of welder is based on the use of two single action forward converter working-pull. Converters operate at a frequency of 60 kHz. Output current can be adjusted in the range from 0 to 140 A. After switching function the welder can operate as a battery charger. Charging current can be adjusted in the range of 0-70 A. The device is powered from a single phase supply 230 V.

Accumulator Charger for Bicycle
Kufa, Jan ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
The aim of this thesis is to suggest a suitable way of charging mobile devices by using bicycle. In the first part of bachelor thesis there are discussed various options for charging the battery on a bicycle, described differences between the alternator and dynamo, and finally the different types of batteries. The second part describes in detail used blocks that were used in the engagement and the reasons of their choice. In the last section there are described the final parameters of the charger.
