Development of voltage instrument transformer resistible against higher harmonics
Mihályi, Róbert ; Odehnal, Martin (oponent) ; Bušov, Bohuslav (vedoucí práce)
This bachelor's thesis describes the basic principles of transformer operation in the first part. The following chapters focus on issue of higher harmonic frequencies. Then it describes the basic design and principles of instrument transformers, which are the main subject of this work. At present, higher harmonic frequencies are becoming more and more common in electrical networks. Therefore, this work tries to bring new knowledge in the issue of higher harmonic frequencies in instrument transformers. The last chapters describe the computational design of an instrument transformer that resists higher harmonic frequencies. This transformer must be able to transfer these frequencies to the secondary winding. It was necessary to study the standards and technical literature related to this topic in order to create the proposal.

Lead-acid battery charger with a pulse converter
Mihályi, Róbert ; Martiš, Jan (oponent) ; Vorel, Pavel (vedoucí práce)
This master´s thesis discusses on complete designing of a lead-acid accumulator charger. Charger operates with the principle of a two-switch forward converter. It contains the design and manufacturing of all the proposed winding subcomponents, the semiconductor components, the control circuit board and the power circuit board. This thesis includes also the design and description of the individual parts of the power circuit and control circuit. The revival of the charger, including a description of the individual adjustments that were necessary for proper and reliable operation is also in the content. This thesis contains too a series of measurement performed to verify the correct function of the charger.
