Converters for HVDC Energy Transmission
Martinec, Roman ; Klíma, Bohumil (referee) ; Červinka, Dalibor (advisor)
The aim of this thesis is to introduce the high-voltage direct current (HVDC) systems used in the world today. The work lists the basic principles of connection between individual HVDC stations, as well as the configuration of the HVDC transmission link. In addition, the work describes the topologies of converters currently in use and also their principal semi-conductor components. In the conclusion of the thesis, the HVDC technology is assessed, including its advantages and drawbacks.

Digital controlled power source with GSM
Buday, Martin ; Streit, Jakub (referee) ; Bradáč, Zdeněk (advisor)
Content of this diploma thesis is project of the digital control design for a thyristor source with GSM communication. Designed for corrosion protection. The work contain design of the whole device from the initial proposals of the electro diagrams up to finished product. It describes the events that arise in corrosion, explains the principle of operating a thyristor as a power switch. It also describes the creation and structure of a simple menu using the STM32 microprocessor. It explains the principle of controlling a source. Next, it deals with controlled rectifiers using a thyristor.
