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.
