Switching benchtop power supply 0-30 V, 0-5 A
Galia, Jan ; Pazdera, Ivo (referee) ; Martiš, Jan (advisor)
This thesis deals with the design and construction of switching mode power supply for lab application. Convertor is based on the forward topology with adjustable output voltage regulation from 0 to 30V and with maximal output current 5A. Antoher features of this power supply is adjustable current limiting function which can be set from 0 to 5A. For closed loop control was chose analogue cascade regulation.The contol part consists of operation amplifire TL072 and SG3525 contorl circuit.

Power-supply generating specified current pulses
Svoboda, Karel ; Petržela, Jiří (referee) ; Šotner, Roman (advisor)
This bachelor’s thesis deals with generation of current impulses, which can be defined in range of few ampers, to resistive load. The first part of this project is focused on analysing of single circuit´s concepts and posibility of theirs analog control. The next part of this work describes whole setup of designed circuit. This thesis includes simulations from PSpice and signal snapshots from an oscilloscope, which prove the functionality and parameters of the whole device. Final section of this work discuss all results achieved during design proces.

Controlling of models using environment of digital central
SCHRENK, Jan
The work deals with creating a model railway, which will serve as a demonstration tool for teaching the subject of automation. Model railway should demonstrate the possibilities of manual and fully automatic digital control with a control panel Roco Z21. It also describes the comparison of traditional analog control and digital. It also contains assembly, calibration and adjustment of the individual digital elements - decoders. A separate section is a Step-By-Step guide for basic setup utility software Rocrail.
