Reducing transformer inrush
Zoufalý, Marek ; Bušov, Bohuslav (referee) ; Šimek, David (advisor)
In this thesis is described the function and design of the transformer designed on ferromagnetic core, composed of transformer sheets. It is explained a transient inrush current of the transformer. In this work is inserted voltage and current waveforms, designed printed circuit board, serving to reduce the inrush current.

Measurement and recording of the initial magnetization curve and hysteresis curve of ferromagnetic materials
Tran, Quoc Bao ; Vaněk, Jiří (referee) ; Klvač, Ondřej (advisor)
This thesis deals with the measurement of primary magnetization curves and hysteresis loop. The thesis is divided into two parts, the theoretical part and the practical part. The theoretical part describes the creation of magnetic field in materials, excitation of magnetic field by electric current or excitation of electric current by changing magnetic field. The practical part is focused on designing, construction and testing of amplifier and the measurement and displaying of hysteresis loop. In the end of the thesis is summarized what results were achieved.
