Resonant and quasi-resonant converters
 Krška, Vlastimil ; Sedláček, Jiří (referee) ; Murina, Milan (advisor)
Project is engaged in concept and realization of quasi – resonant converter with switching in minimum voltage which derive benefit from resonance capacitor and inductor. It is one of the possibilities how to increase efficiency of switch – mode power supply. While using resonant converters the losses are reduced, when the resonant inductor will connect and disconnect at zero current in inductor, or at zero voltage on inductor. Base of the power supply is chip NCP1337. Concept comes from detailed analysis functions of integrated curcuit and others curcuits of switch – mode power supply. Project includes a complete concept of all partial curcuits, description of a construction and the main parameters measured on the realized sample.

Construction and Realisation of the High Voltage Power for Probe Cleaning
 TŮMA, Zbyněk
This work is focused on the construction and realization of voltage source for cleaning of Langmuir probe. The work shortly acquaint with the questions of probe plasma diagnostics and the potential problems of her application in plasma, where comes to pollution of diagnostic Langmuir probe. The main part of this work is the analysis of the technical solution of cleaning Langmuir probe. The output of this work is the concrete technical solution and realization of voltage source for cleaning Langmuir probe.
