Dual channel bench power supply
Stehlík, Ota ; Brančík, Lubomír (referee) ; Kubíček, Michal (advisor)
The aim of this thesis is to design and construct a two-channel bench power supply with variable output voltage in range from 0 V to 25 V with a maximum output current of 2 A. At the beginning of the thesis a general principles of power supplies are summarized. In the following section a detailed design description and simulation results of the main power supply are given. Afterwards, the design and description of auxiliary power supply with electronically controlled fan is presented. Finally, measured characteristics of the bench power supply are given.

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.
