This work builds on a semester project 2 from the winter semester of this academic year. The aim of this thesis is the design of converter using semiconductor components based on SiC technology. This converter is used in the construction of quick charger for electric vehicles. The design of this converter must be based on the requirements for compliance voltage safety. It describes the design of power components used in the construction of this facility, the determination of their losses and determines the overall efficiency of the converter. There is also proposed mathematical model of high-frequency transformer and made his simulation in Matlab-Simulink.

My thesis is focused on realization of three inrush current limitors samples. This limiters will be used in ABB´s metal-clad, air-insulated switchgears for medium voltage distribution. On the basis of the results there is chosen the sample with optimal properties suitable for practice in the conclusion.

The aim of this diploma thesis is to continue in prototype realization and a final proposition of three-phase frequency transformer pilot projected in scope of my bachelor work. This transformer is outlined for a small unsynchronized engine to 100 watt output and is designed to supply the fan motor. This suggestion was optimalized from the standpoint of bargain low price and technical feasibility. Powerful part of transformer is solved with help of circuit FSB50450 which is fed from compact source MYRRA 47155. Steering system is guaranteed with circuit MC3PHAC. This device is possible to use in less demanding applications where it was resisted by high expensive price of common frequency transformers.
