Analysis of Current Higher Harmonics Impact on Losses in Transformer Foil Winding
Žďárský, Jan ; Klíma, Petr (referee) ; Mrajca, Miroslav (advisor)
This paper deals with the analysis of the effects of non-sinusoidal current on the foil windings of power transformers. This issue is important in transformer design since losses are measured only when sinusoidal current is passed through. In some applications, these losses need to be recalculated to account for the effect of higher harmonics of the current in actual operation, as these losses are related to transformer heating. A literature search of available sources that have already described this issue is performed in this work. In this paper, a model for simulation in Ansys Maxwell environment is presented, using which the losses due to higher harmonics will be calculated.

Laboraty Pulse Power Supply Using Output Linear Stabilization
Lednický, Marek ; Dušek, Martin (referee) ; Šebesta, Jiří (advisor)
This thesis deals with switched mode power supplies. The theoretic part of the thesis consists of historical development and the elementary schemes of switched mode power supplies. It also includes the comparing with linear regulators. Next, it contains the description of individuals parts switched mode power supplies as a rectifiers, power supplies and stabilizers. There is a proposal and fixing of laboratory pulse power supply using output linear stabilization in the practical part of the paper.
