Educational tool with power supplies
Junasová, Veronika ; Šteffan, Pavel (referee) ; Levek, Vladimír (advisor)
This work deals with design and realization of board with numerous power supplies. It includes linear power supply, switching supply without inductor, switching supply with inductor using step-up and step-down converter. The board allows to choose between various output voltages, several input filters, output filters, loads and it enables to measure the temperature of used power supplies. It can be used for education and practical demonstration of basic properties, advantages and disadvantages of these supplies. Part of the thesis is a description of power supplies for low voltages, design of educational board and demonstration of results.

Study of Equilibrium Magnetic Configuration in Tokamak Type Devices
Havlíček, Josef ; Tichý, Milan (advisor) ; Kubeš, Pavel (referee) ; Van Oost, Guido (referee)
This thesis presents the magnetic fields of the COMPASS tokamak and work done during the COMPASS reinstallation in the Czech Republic. The geometry, vacuum magnetic fields and Power Supplies for the poloidal field coils circuits are described in the technical part of the thesis. The design of Power Supplies filters and improvements in the controller algorithm are also introduced. The MHD equilibrium reconstruction code EFIT++ and implementation of the induced currents model are described in the physical part of the thesis. The EFIT++ code was adapted for COMPASS. The utilization of the EFIT++ code for the COMPASS operation is shown. The global power balance in the non-stationary phases of the tokamak discharge is explained and examples are shown. The attached articles describe Power Supplies and tokamak feedback system developed for the COMPASS plasma control. Powered by TCPDF (www.tcpdf.org)
