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.

Laboraty Pulse Power Supply Using Output Linear Stabilization
Lednický, Marek ; Dušek, Martin (referee) ; Šebesta, Jiří (advisor)
This thesis deals with switched mode power supplies. The theoretic part of the thesis consists of historical development and the elementary schemes of switched mode power supplies. It also includes the comparing with linear regulators. Next, it contains the description of individuals parts switched mode power supplies as a rectifiers, power supplies and stabilizers. There is a proposal and fixing of laboratory pulse power supply using output linear stabilization in the practical part of the paper.

Charger for a battery supply of an oscilloscope
Novák, Miroslav ; Martiš, Jan (referee) ; Vorel, Pavel (advisor)
This bachelor thesis deals with the design and construction of a battery charger for an oscilloscope battery source. The output parameters of this charger are: output voltage 4.1 V and output current 15 A. The charger is designed as a flyback converter controlled by the integrated circuit UC3844. First, the possible topologies of the inverter are described. Then the selected flyback converter and the subsequent design of the power parts and the control circuit are described. Then the measurement where the transformer leakage was too large is described. Therefore, the following section describes the modification of the charger design, which uses a snubber network to eliminate the effect of leakage. This is followed by a description of the mechanical design of the charger. Finally, measurements of the charger are documented, testing problems are described, and the results obtained are evaluated.
