Design inverter using semiconductor on based SiC
Kharchenko, Vadym ; Procházka, Petr (referee) ; Kuzdas, Jan (advisor)
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.

Off-line supply source 15 V / 1.5 A with a galvanic separation for a laboratory equipment
Pokorný, Vladimír ; Tománek, Radek (referee) ; Vorel, Pavel (advisor)
This bachelor's thesis deals with the design of a single-acting switching power supply for a laboratory equipment. The required parameters of the source are input voltage 230 V and frequency 50 Hz, output DC voltage 15 V, and output current at least 1.5 A. The introduction of this thesis briefly describes the operation of flyback converters. The next part is focused on the design of the high-frequency transformer and the main power part. The work continues with the designing of power components and heatsinks. The following part is the design of the control part, which will use an integrated circuit from the UC384x family, and the construction of the power supply. The conclusion of the thesis focuses on the source debugging and verification measurements.

Resistive Heating System for Work Shoes
Pár, Lukáš ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This bachelor thesis deals with the design of a device for the resistive heating of work-shoes, the circuits of a power converter for a heater and the battery-pack. Two variants of the heater are designed in the first part of thesis. Thesis continues with design of DC/DC converters for both types of the heater. Next part of the thesis deals with a design of the battery-pack with simple BMS circuits. The design of the control circuit for selected DC/DC converter follows. Next part of thesis deals with the construction of the device. Last part is dedicated to measurements and verification.

DC/DC converter 24 V / 350 V / 100 VA with a pulse transformer
Pár, Lukáš ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This diploma thesis deals with design of DC/DC converter which will be used in one-phase inverter powered from batteries. Required parameters are output power of 100 W, input voltage of 24 V and output voltage of 350 V. In the first part is briefly discussed used topology of flyback converter. In the next part is designed impulse transformer with a request to design impulse transformer as small as possible. Thesis continues with draft of power components placed on primary and secondary side of converter. In this thesis is part about limitation of voltage overshoot at turn off transistor. Next part of this thesis deals with the design of control circuits using an integrated circuit from the UC384x family. Thesis continues with the production and debugging of the converter. At the end of this thesis are measurements confirming the correctness of the proposed design.
